Cat Dominant and Recessive

The most significant of these three possibilities is the effect of the alleles that ate not equal: short hair plus long hair gives placer to short hair. It is this way due that the gene for short hair is considered  dominant and that of long hair as recessive.

The dominant genes always “win” over the recessive. If there is no dominant gene in the aloe, as in the case of the genes of long hair, then the recessive genes can transmit  its features to the whelps.

This happens with the genes associated to the length of hair and also with those corresponding to other characteristics, as is the color of the cloak, the shape of the ears and nose, the corporal constitution in general, the length of the tail, etc.

Some are dominant and some are recessive, and all perform a role in the dancing of the genes that have as a result the creation of a new being. If history would end here, recessive features as of the long hair would be less common with the passing of generations and would disappear at the end.

In the combination of genes of successive generations, the recessive genes will always loose. But although the recessive gene doesn’t perform any role in determining the length of the hair of a whelp in the mating, it is equally transmitted in the cells of that generation.

If one of those whelps ends to mating with a cat that also has this recessive gene of long hair, it is probable that some of the resulting whelps will inherit the long hair.

This explains why certain physical characteristics disappear during one or ore generations and afterwards reappears.

Inheritance
The inheritance is the transmission of the characteristics of one generation to the next, which gets complicate with the intervention of other factors.

In first place, although most of the genes are inherited in a very independent way from the rest, like the gene of length of hair, cats that present the color known as tortoise are an example.

The color of the cloak of a cat comes determined by its genotype and the genes of color form part of the cells that constitute the skin.

As the genes of the color red and black are found in the X chromosomes, the females can have the color orange (red, in the feline context) and black, that together form the tortoise hair color.

Males can inherit the red or black color, but not both, due that they only inherit one X chromosome. In consequence, almost all the tortoise color cats are females and the few males that are born with this hair color are almost always sterile.

That’s why the say that the orange color cloak (red) is “associated to sex”. There exists other association that don’t imply the X or Y-chromosomes, but that give place to certain features to be inherited together.
