Are Orange Cats Almost Always Male

Which almost 99999 of the time is sterile.

Are orange cats almost always male. Although the research is far from definitive male. However they only exist in much smaller numbers and male cats make up the vast majority of all orange tabbies accounting for 80. Calico and tortoiseshell cats however are almost always female.

The Male Dominant Influence in Orange Tabbies. Since females have two Xs and males have one X and one Y this means that a female orange cat must inherit two orange genes one from each parent whereas a male only needs one which he gets from his mother. In the exceptionally rare cases where the male is not sterile about 1 in 1000 of the already rare 1 in 3000 male calico cats attempting to breed him with a female calico or tortoiseshell will not produce male.

Orange tabby cat toms outnumber queens approximately four to one. The gene responsible for the orange color is sex-linked resulting in a much higher likelihood that an orange cat will be male versus female. The color of a cats coat is closely linked to its gender.

Males with only a single X chromosome will be either orange or black. Calico cats are almost always female because the locus of the gene for the orangenon-orange coloring is on the X chromosome. It has to do with the X chromosome which has genes for fur color.

Heres how it works. Melanin decides the final coat color and an orange fur results from one gene changing the expression of another which can change black pigment into orange. Black coat color is not found in male cats.

Orange coat color is not found in male cats. Orange tabby cats are about 8020 male to female. Random X-inactivation during early development results in patches of orange and black.
