Ticked tabby also appears to mask spotted tabby (Sp-). Father. This is a trial pedigree produced using the Professional Edition of Breeders Assistant for Cats that includes coat color predictions for the expected offspring. Figure: Genotype for Seal Siamese in Cat Details Window. The original calculator, simplified to be usable with very little genetics knowledge. This creates the pigmented bands along the hair. These broadly divide into coat type genes: longhair, wirehair etc., and some genes that are really congenital defects but which are considered normal characteristics for some breeds e.g. The Cat Rental Store is here with equipment rentals and services for any application. It's common for those who are searching for a new cat to already have certain breeds in mind from their past experiences. You first need to choose the specific number of cat breeds you'd like to see, then click the button to generate them. The most important genes that affect pattern are the various tabby genes. On the shoulders there is a light "butterfly" pattern, and three thin stripes down the spine. American Bobtail, blue tortie silver shaded, Breeder: Isa&Neo ~ Home of the Kurilian Bobtail ~ (#85299). This is a gene with symbol O and is probably the most interesting gene affecting cat color/pattern from a genetic point of view. The various tabby genes are covered in more detail below. This gene has a lightening effect on eumelanin only. There are several forms of tabby pattern in the cat:- mackerel, as seen in wild-type tabbies- blotched (classic) tabby- ticked (as exemplified by the Abysinnian)- spotted (e.g. Black Black, carries chocolate Black, carries cinnamon Chocolate Chocolate, carries cinnamon Cinnamon. The Agouti protein causes a banding effect on the hair: it causes a fairly sudden change from the production of eumelanin (black/brown pigment) to phaeomelanin (red/yellow pigment). Hicks noted that all colors and patterns can have some white. These effects are impacted by other genes as well as the width of the bands in tabbies (which are also genetically determined), and its formation depends on the expression of the number of genes and their interaction. Its effect is to replace all the eumelanin in the growing hairs with phaeomelanin. Hi ! In cats, the red and black colors are on the X chromosome, Hicks explained. Mating certificates are only available with the cat and dog versions of Breeders Assistant. Robinsons Genetics For Cat Breeders & Veterinarians, Fourth Edition, Butterworth Heinemann, Boston, 1999. Female cats carry two copies of the X chromosomes in their cells. This article will use the 'genetic' color descriptions. I strongly advise it's use, and I'm probably going to end up referring to this quite a lot. {"id":"", "email":"","default_address":null,"first_name":"","last_name":"","name":"" }. This color should be noted as it is the color that the white is masking and the color that the cat will breed as when an adult. The gene coding for the tyrosinase enzyme is the C gene. Many breeders have, understandably, associated tabby with the Agouti (A) gene because of the effect of the non-agouti recessive self form (aa), however the tabby patterns themselves are not controlled by the A gene; what the A gene controls is the degree to which the tabby patterns will be visible (either highly, especially in an eumelanistic coat, or hardly if at all).
