Mendel's 1-st law. All can be simplified. And so Mendel's first law for Tonkinese will sound so: hybrids of the first generation are uniform. At crossing Siamese cats with Burmese it is received 100 % Tonkinese litter.
Let's take for an example brown (BROWN) Burmese and Siamese a seal - point. Accordingly we shall write down a genotype (is simplified):
BBDDcscs - a seal - point
BBDDcbcb - brown (BROWN) Burmese
Let's reject the general data and we shall construct lattice Pineta only to one attribute Result it is seen - 100 % Tonkinese litter.
I want to calm at once owners Siamese: animals of new experimental type for deducing are not suitable. Here just right so-called "Thai" cats. We in club long did not know that with them to do, cultivation Tonkinese has given them the future, and Siamese a high level has opened new prospects. I think, it is not necessary to speak why, all factory owners know about it Siamese.
Mendel's 2-nd law. A rule of splitting of the second generation.
In the USA Tonkinese are supposed to pairing only with Tonkinese. And here again a problem: in result 50 % Tonkinese, 25 % Siamese and 25 % Burmese kitten are born. And the same second law prompts all to us, that the genotype is equal this situation to a phenotype. On experience we were convinced, that it is not necessary to invent a bicycle. Knitted Siamese the second generation against each other, and did not receive anything, except for Siamese. All is simple:
BBDDcbcs - a natural mink.
Here ours 50:25:25,
Or on a phenotype - 3:1,
Or on a genotype - 1:2:1.
All trouble that very much frequently factory owners do not want to reconcile that half-litter goes in domestic favorites without the right of breeding cultivation, but is inevitability. It was necessary to me on " a duty of service " draw off litter artful factory owners, more often the cat - Tonkinese is tied on a cat - Burmese. But, alas, such mountain - genetics do not take into account (or do not know): the first that these lose kittens is a color of eyes. Alas, but in fact it is one, if not main, rockforming an attribute. Especially it is appreciable there where cats Burmese have lines of blood from nurseries FIFe as at them flavovirent color of eyes is allowable under the standard, and at kittens pseudo - Tonkinese from such eyes of color of " a wood nut " or " marsh ooze ", but in any way aquamarine are viscous. It seems to me, that in so rare breed similar experiments are inadmissible.
