With it pass from the years, as emphasized hair races news have developed, the term “Rex” generally is used for refer to some race that has a mutação of hair, then, a “Rex Cat”. Although the Sphynx be not considerado a Rex, should be mentioned here that this is an evident one mutation to the hair, occurring like this no hair, but also due to his relationship with another Cat Rex, the Devon Rex. The Sphynx and the Devon Rex genetically are related a for another. When they crossed between itself, more or less, indistinct little cats will be born nudes. A Cornish and Sphynx and another Rex will give hairy cats. Even a Sphynx and another one breed of little hair (scarce) will give hairy cats, therefore other breeds of little hair are genetically hairy cats, but fenotipaly bold. Then, it has occurred other mutations of cats scarce hairs that do not be acquaintances by the public in general, neither developed in the breed, however, were completely dominant. Like this these cats of little hair could have produced naked kittens, simply because his dominant marks annulled another I draw any. The Don short hair and Peterbald are genetic looks like naked, however this bareness is incomplete or have expressions variables, then this bareness varies between cover completely (and in part) emphasized for cover the bald one.

MAINE WAVES BY DAVID BRINICOMBE

MaineWaves coat is like Aldebarano (down the picture) : Undulated (emphasized ), instead of curly. The hairs are very soft and hot to the touch. Since this picture was removed, he has grown with a gola of hair, except his tail, has not moved very. Aldebarano is a pleasant cat. He shares a room with his castrated brother, Betelgeuse and its son Regulus, and the three require that you embrace them immediately when enters in the room.

MaineWave is not a new breed, but is barely a given loving nickname by me, David Brinicombe* for some few “MaineCoons Rex” that has remained as a result of my “Elimination Rex Program”. Of fact, they could not form a new breed as a MaineCoon 100% in their Pedigree, but would be able to be to the least, considerateds like a new range inside the MaineCoon breed.

Discover about Maine Coon Rex


In the end of the years 80, in the direction of some line, reproducing with a good line of Silvers, the MaineCoon Rex did her appearance in the great britain. It arose in other lines also, showing be, since then, you handled in your genes recessivos. The intial reaction was a horror in the appearance of strange little cats. The persons asked: Of where did these come kittens? They are fruits of an outcrossed deliberate or accidental? The setting soon was being established for controversies.

In its original discovery , you had were recommended. You quiz of mating were carried out , introducing Devon and Cornish Rex in the lineage. Considering what was for happen afterwards, intially the initiative for this kind of experience was an act of boldness! There is always a lot resistance for the crossing between genealogy of peculiar races, and with MaineCoons outcrossed (without consangüinidade), little probable , therefore the rigorous culture about the approach Outcross limits crossings consangüíneos, what will say between peculiar races. The result of these limited you quiz involving peculiar breeds in matings was negative film strip for inconcluideds, but they indicated perfect that MaineCoon Rex was not a result of an outcross recent.

You analyze of genealogy and other researches aimed for 3 cats that had been imported for the great britain, but these were evidences circunstances , barely based in cats that appeared more frequently in genealogies of Rex. Cats key (suspicion of will be bearers of the gene Rex) were dead persons, castrated or unavaliables for them you quiz and nobody outside of the great britain had vision for relate any cat bearer of the gene Rex. The mold of inheritance of the gene Rex was clearly recessive instead of dominant , what becomes more “difficult” than “right” ; about the roads of the hereditary inheritance for this new gene.

An experience that never to have been deed before was carried out, essentially for be obtain more certainty than genetically involves a gene Rex for another be duplicated Rex. It is necessary still verify itself an ONLY gene recessive was involved in the trial of the mutation Rex. This many times is considered , but uncertain, therefore the sprouting of MaineCoons Rexed pierced broadly , including hard the hair curled for barely straight hair , indicating that there is more of an ONLY gene involved. However, privately I have a theory that can explain the as much as one I attributed a Rex for a gene basic recessive, but my theory is related to an essential characteristic of the MaineCoon.

The delay of Roy Robinson (British specialist in feline genetic) to give an opinion about the discovery was extremely helpful. He normally treats these questions about feline genetic, and suggested that the gene Rex can be a consequence of a gene dominant incomplete, as well as the existence of several possible other anomalies drawn in a genealogy. Or be, where the problem began. There were some probable hereditary roads about each one of the cats bearers of the such gene for they will result in “rex deliberate”. Theories about the wild origins began it arise sudden.

A decisive conclusion had that to be taken about the new event of Coonies bearers of the gene Rex. It been the discovery deed, some doubts arose:

1 - Become-Read public?
2 - Divided-Read between the involved Breeders or
3 - Maintain-Read in confidential?

To first option (Option 1) : Go to public, in that moment, looked to be the scientific and most sensible idea. The only problem is that many creative felines do not be sensible or scientific nothing. Half of them understood or grossly misunderstood that genetic beginnings are used for despise others cat breeders or for promote them. To simple mathematics of divide for two is not appreciated and any cat with any supposed shipment in his Pedigrees are marked down as shipment of them own, even if this factor be of bass risk, but still can be acceptable. The Panic of breeders about his stocks of reproduction , declare “as improper” for that nobody expect for these kittens. I Consider this kind of attitude as “press”; for do not tell “devastation” regarding the new discovery of the Rex gene.

The Monday option (Option 2) : Say barely to the creators that can have animals bearers. The problem is that this would be able to to be seen of negative form and as an objection it to be exceeded amid a gross panic. Except some persons had the correct information about the discovery and this would be very difficult for to be gone over again of sensible and coherent way to the others Creative , from the moment in that the discovery of the gene Rex becomes acquaintance , they would not be able to not understand-read correctly in their conceptions. This option, agreement with the British noble art of the “meio-termo”; has tarnished this story because of premature columnists presents of our reality. Most of the conflicts of the modern world, has finger (opinion) of an or of another sensacionalist British of the media infiltrated in the environment of the creation (printed media mainly) and do not I give up this idea as being to more sensible of the options. There is a more worse option than this – see down.

To third option (Option 3) : Maintain everything in secrecy, would be still to more worse option. At first sight, looks pragmatic. “The that the eye does not see, the heart does not feel”. It is pragmatic to that you involve cat breeders and your rumors. With this option, the combination of ignorance with invention is more unproductive still and, in case of, my knowledge would be compared to the ancestor of the most greatest lunatic, reproducing theories that were invented.

There is a Wednesday option (Option 4) : Foresees the dilemma of the hereditarity above all for any one of the three first options, more this should be grasped since I initiate him. The Option 4 would be helpful for declare a new one gene, an acceptable and smaller problem in a level of smaller incidence. This option disarms the most poisonous creator of problems and, everyone be able to have the gene. Of any way, however nobody was imported in foresees to hereditarity in the afraid epoch or I fear of that cats bearers could be despised, unfairness by will carry the gene Rex, motive of prejudice by stories invented.

Another harmful fact for the discovery of the gene Rex was an accusation that a new breeder generated “de purpose” or “without want” (do not I know what was more worse!) the crossing of the MaineCoon with Cornish Rex. This also it supposes that creative involved in the discovery has falsified Pedigrees. Even that the gene Rex has arisen of you quiz of matings, the results for a possible connection involving the race Cornish crushed and was tried scientifically that the gene Rex with the Maine Coon swims have to do with this or another one race of complicated hairs or somewhat related to an outcross that I have been done in the epoch. This was the inconvenient one that a certain new breeder generated, by be layman and outdated of the true information that cause to mutation of the gene Rex. Today he dependablely would be able to to be slandered by inconvenient size.

It is, in the however, impossible one eliminate completely a rumor as this , where do we be able to imagine the polemics that the persons believed about the results that a recessive gene can promote, even if less harmful. I am not suppressing information here by do not list some humble genetic pair, but itself someone really has more intentions of cause more mischief about the matter for denigrate new the discovery of the gene Rex, obviamente this person would be capable of say any thing for detonate the theory of the gene Rex in his malice, as well as hackers are utilized its own malice for create virus for writers computer.

But, it imagines now the victory of the theories of conspiracy when a Maine Coon, ironically by be called “Cornish Cream” more latter verified to be a bearer of the gene Rex!

I said that had the answer for the discovery of the gene? Not! But I expect to be able to build a convincing argument here of as do not do this, therefore consider like to more worse of all the options described above as the Option 3 succession after a convenient break by the Option 1. Oh, that amused, if you will go a breeder cannot want be involved with this experience!

First, it stayed involved with the discovery in 1993, when I acquired a huge queen (queen) jointly with 8 coming kittens of another breeder. I did not know, in that period of training, that the father of the brood, a Maine Coon male called of “Cornish Cream”, was a cat bearer of the gene Rex, and itself someone knew, would not be telling. (The Option 1 had more influence in these moments).

Facts were leaking quickly and circulating for there outside. I had heard some information about the possibilities of the gene Rex for Maine Coons in that epoch, and I was confused by desinformações conflitantes when then, I decided to take mine own decisions. My news brood be going well with 2 boys (in private that were charming my eyes) and a girl, a charming one Silver of ashen tones (and I did not imagine that MaineCoons could be so ashen). I studied the Pedigree by a long time and, with a lot endeavor, I concluded that any cat that Myself had news, was associated with the gene Rex, therefore certain cats of long hairs, in some moment, to the long road of the development since the primórdios of the race, possibly they were, then, in my conception the risk about the discovery of the gene Rex for our race was very small. Then, it stayed with the male kittens.

That times, I didnt secret of the fact that Myself to have selected these 3 for reproduction (with the supposition that they had a level under risk for the gene). The “cacarejar” ; of languages in that period of training continued about the possibilities of the gene Rex for the Maine Coon breed and in addition, without any proof or a better evaluation about the gene Rex and this would be a disastrous problem. Nobody came to me for me advise “que I should use no of those little cats”, but even so, me mantive requesting information. A rumor came to the surface of that “Cornie” (the cat sold, father of my cubs ) be able to have paternity recognized of 2 cubs Rexed with a queen without name, but this was barely a rumor and any sufficient dependable information for take attitude was distant. With observation in the past, everything this that I knew, simply is not going to be confirmed today by the responsible, that still remain without confirm absolutely nothing.

Then, “the axe cut the firewood”. A certain specific rumor of a merchant of cats, which personally did not know , came cheerfully with the news that Cornie was a bearer , and with him, the others 2 cubs Rexed of paternity recognized. I verify this information new with someone that much trusted and this person told me that really the merchant knew things to more about the matter. I had not delivered another cub still, although already had removed the check by the sale of the even. Then, due to this, I canceled the sale and I returned the money.

Now I was in the vagueness. Cornie had been sold and the fofoqueiro told me that he to have been castrated. I followed the trail of the new owner and I defended him for its integrity, but finally, the new holder really to have castrated Cornie. I talked about the gene of the discovery with the new holder and I could perceive that they were really distressed by will have discovered that their new acquisition was a Rex bearer. Cornie has paternity recognized in an I number of champions TopShow in his lineage and until today, when I think of him, I feel distressed and regretd by to have sold a cat of the stature of him, in my creation. Without it speak that also finished in crying the loss of that another business. (The sale of the cub).

I Pretend to speak of the history of the MaineCoon Rexed, but in the context of (not) deal with genes undesirable. More than evasive, the experience would be able to be repeatedly and unfortunately has been repeatedly, as well as other genetic anomalies, absences, defects, does not import what are or are called. The most important one is like you identifies them and as evaluates them. Refer-itself to the book of Roy Robinson and he gives two “aceitáveis” levels for genetic abnormalities: 5% for some grave little anomalies and 1% for other more severe. I had supposed that a coat emphasized to be an annoyance that would be better do not work for improve, however inconvenient enough for the majority, if inserting for elimination of undesirable characteristics inside the 1%.

Roy Robinson was a priest of the high genetic one felina and I worship the good sense in its book. While is open, permit-me do a citation : “Exemplos are known...[] where a lot broad admiration by animals used, subsequently have been found for will be bearers of an anomaly recessiva. “Earth the reproduction”, in the nose! []...In The end of them yourself count , will bring the gene for the interior of the race, being imprudent the same anomalies. “Breeders suddenly are able to feel confronted with himself own” with identical problems of preservation of the race and, at the same time, of elimination of genes that cause the anomalies”. Prophecy of fact!

In the britain, this is seen like kinds of breeders that did not read Roy Robinson. Bases of an or two explanations of premature deaths , therefore the “gene Rex” was declared like a gene causador of mischief and to “mensagem of nutritious substance” was pressured for that the gene arrived to the refrigerator.

Finally , it having been choosen, therefore the Option 3, sufficiently by a long time for that the rumor circulated, a such “lista unknown” was published, citing a recorded bearers cats relation. Consequently, the effects of the Option 1 were envocados, therefore everything came to public and breeders with some relation of those lines in her Pedigrees were aim of critics and repercussions, having her cats despised by the public. Many they gave beyond than arranged for will continue having a hobby happy in the breeding. Others imported stocks Rex “freely”. The reputation of the MaineCoon British original was prompted it be to more tuxedo of all of the times. The rumor had run of a side for another, blasting as calls in the United Kingdom.

At the same time, in 1994, was said to castrate all of the known male bearers, but barely for remaining females bearers. Everybody the others cats were free for will procreate. I to have been done an exception : unknown Males or not-bearers would be able to to be maintained entire for the matings.

I decided to quiz mating the son of Cornie, the little cat of white paws, now a magnificent immaculate one Silver Tabby that would be able to come to become a great Champion. I did not be necessary quiz-read , but this was seen by me as a responsible thing of be done. He tried to be a bearer and I pair of use-read, except for you quiz of mating. This also gave final evidences for try that Cornie was, of fact a bearer of the gene.

Meanwhile , the Club placarded that Rexed kittens would not be born more. We conquer a problem? Expect a little... how Many male bearers are in use now? As much as females? The answers are: barely no male and enough females, respectively, seen is necessary two bearers of the gene for do a cat Rex. Like this, if all the genetic influences of conduction have been eliminated, any kitten Rexed will be born for carry females.

There are estimates of that 10% of male bearers they will be detached much more quickly than females bearers. This is for cause “of influences” will be much more evident in the partners than in females, therefore fêmeas have around 6 to 8 matings in all her helpful life, generally less times than the males can mate for obtain same influences for the gene. Therefore, an influence for any gene known would be able to be deed in barely a month (in barely 1 ONLY mating) with the work of the best male of an alone time, and in the majority of the times, with peculiar fêmeas, instead of we will expect hereabouts 6 years utilizing females.

Analyzing the facts, is really improbable that a fêmea even is going to find a bearer randomly, while a male that contém the influences of the gene is more probable for mate with an or more females bearers, then male bearers are more probable of will be found and, consequently eliminated.

To political of it eliminate the male bearer does nothing for limit any female bearer, avoiding its transmissions of his genes Rex. But, certain the proportion of bearers was divided in each generation. Yes, however itself more than 2 cubs for time of life will go used for reproduction, and the gross number of bearers encobertos go up beyond on average to each generation, they finally will back and will cause a new one Rex panic in the future.

If you will go against you had of mate, to last chance for uncover some news bearer is virtually no, and any recessive geneis between us for stayed.

As it would be able to be to alternative of the political one of elimination then? If you are happy by live together with the gene Rex, follow the beginnings and tolerate the occasional kitten bearer. In his peak, in more or less 1% of little cats that are born, cubs Rexed were in well bigger number by the sub-development (despised) and amid cubs with more worse anomalies (result of the experiences with the gene). I believe that I have presented that Rex is an I draw affable that does not do difference to a domestic cat of the same skill that others short hair or Rex breed.

Permit occasional or proportionally the birth of cubs Rexed also is going to permit that these are tracked, in order to avoid Rex inside the breed. The preferential option would be in prohibit you quiz them of acasalamento, with the intuito of efetivar a grave politics and more guaranteed for study better this kind of reproduction Rex, still little studied during everybody these years.

Remembers that the Option 4 proposal above? Accepting the gene and deciding live with him? If creative had determined with the political one of some behind , enough years of harshness and hostility can be avoided. The MaineCoons breeders could have been a hobby pleasanter for everybody and we would not have lost a line of Silvers Shaded of first class.

Unfortunately, still we are far away too for implement the Option 4, but could have happened. The final irony that myself that was to of that the MaineCoon Rex has been shown by the Continent and has certified awarded. That marvelous and healthy attitude for the genetic curiosity and that contrast bitter for ours harmful attitudes here in the gran britain.
