Blue TortieDark blue tortoise shell
An indigenous shorthaired tortoise shellfish.... Some single whites and bright hairspots are apparent, but they are small in comparison to the brightly coloured cats.... Feminine "torbie"-cat with the typical tabby-pattern and tortoise shell-colouring. Tortie and chattun are the results of an interplay between genes and evolution.
It is the main fur colouring ( "B") genes for the colours browns, chocolates, cinnamons, etc.). can be masking by the co-dominant O on the X chromosome and has two halels, the O (XO) and the non-orange (Xo), which each generate phosphorus colored phaeomelanine and eumelanine pigment.
ANNOTATION: It is typical to take the letter for chromosomes out of their contexts, and the allele is labeled only with the capital letter G for the oranges or the small letter G for the non-oranges. Tortie and chinchillas are listed: Converts crème from oranges, grey from blacks, etc. Different words are used for certain colours, e.g. grey is also named grey, while oranges are also named amber.
Therefore, a tortoise can be a tortie or a blue/cream tortoise or similar, on the basis of the gene Allels (B) and (D). Like other mammals, the feminine feline tissues have two XXs ( "X" chromosomes) and are subject to the phenomena of inactivation[ 11], in which one or other of the 12s is randomly switched off in each of them at a very early stage of evolution.
In which the chromoosome bearing the halogenated alkyl (O) male labeled with ( ) is inactive, the alternate non-orange (o) male labeled with the (B) genes is expressed. In which the non-orange (o) Allel is inactive, they are expressing the org. Two-coloured tortoise pussycats are relatively early, and the two different kinds of cytology mix and produce the typical brindle look, which consists of an intimate blend of red and white tortie and occasionally small scattered patches of red and red.
Like other mammalian thericas, a female has only one Y - and one Y - chromosome (XY). There is no deactivation of the skin of the X chromo-some and the colour of the fur is defined by the presence of an Allele on the skin of the cats. Accordingly, the fur of the kitten is either completely red or not so. Most seldom ( (about 1 in 3,000) a tortoise shell or chattun is given birth; these usually have an additional X-chromosome (XXY), a state known in man as Klinefelter disease, and their cell undergoes an X-inactivation procedure similar to that of women.
Like human beings, these females are often aseptic because of the gender chromosome imbalances. A few masculine chimera or tortoise patch cat can be chimera resulting from the fusing of two (fraternal twin) embryos with different colour types; these can only give one colour to their progeny, not both, depending on which of the two initial ones their testicles originate from.
