So is the kind of cat that looks like it's wearing a tuxedo a single chromosome pattern kind of thing? My parents and I have had a few of those as I grew up, all male. My Dad's first one he found as a stray in his early 20's who apparently was male enough to make more cats and unhappy apartment neighbors before he was neutered. Ironically for this conversation, he though he was a girl at first and named him Virgina or something like that,and when he found out it was male changed the name to Virgil, which I think is a way cooler name.

The gene that determines orange or black fur is present on the X chromosome. For a tortoiseshell/calico, a cat must inherit one of each gene from each parent, something only possible for a female or a male with a chromosomal abnormality. The resulting phenotype is a cat that is neither black nor orange, but has random patches of both over her entire body. Patches of white, as in tuxedo cats or calicos, come down to another gene entirely, a form of piebaldness which is not sex-linked. Actually, in general cat coat genetics are insanely complicated. My favourite cat colour mutation is the siamese coat pattern, which is a temperature-sensitive deactivation of an enzyme involves in melanin production. Warmer areas of the body have a reduced ability to produce melanin, while the cooler areas of the body -- the face, legs, and tail -- are more or less unaffected, and are normally pigmented. Siamese kittens are born white, because in the womb they're uniformly warm.

What I always found weird was how yellow cats are mostly male. Like only 20% of yellow cats are female. I wonder why that is.

My guess it's a recessive gene only found on the x chromosome. A female cat will need to have it on both x chromosomes and inherit from both parents, whereas a male would only need it from the mother.

I've heard white cats with blue eyes have a higher incidence of deafness than other cats. Heterochromatic white cats are also more likely to be deaf in the ear that corresponds with the blue eye.

One of my cats is like a "reverse siamese": it is white where siamese are usually black (legs and most of the face), I wonder how that happens. edit: the cat (he is called Feioso)  edit 2: that aint a funny picture at all, sorry.

He looks like a cutie.  My guess, from what I can see, is this is a layering of things. Genetically a black cat, with the siamese point mutation, and then a piebald gene on top of that which affects the paws and muzzle. Cat genetics are complicated, like I said. Is his body the buff sort of colour siamese cats have?

Johnny Aztec posted:How about this: a cat can have kittens from multiple different fathers in the same litter. It's really obvious if you learned basic biology or sex ed and think about it a moment. Most sexually reproducing species can, including people. Doesn't come up often, but there's at least one twins' fatherhood dispute that ended with three people becoming aware of the fact, and I wish I could have seen all of their faces.

There's a deaf orange tomcat somewhere in my old hometown. My parents have a black/brown female norwegian forest cat that's usually on pills, but once in a while they let her run go free if anyone wants kittens, and they always come out short haired, all black or orange, and often deaf. And twice we have encountered stray deaf orange kittens that have nothing to do with my parents' cat. Or it's a super powerful gene.

Your handsome boy is a snowshoe siamese, a breed resulting from the crossbreeding of a Siamese with an American shorthair. Looks like he's got a bit too much white on him to be breed standard but he is still beautiful!
