Is there some sort of dominant chromosome that makes black cats female? I know about four or five people that have had black cats (including me) and they were always female.

no. the chance of getting a black female cat is 50%, I have 2 black cats, ones a female, ones male I also volunteered at petsmart to take care of the cats and of the black ones I saw it was roughly half of them were male, half were female. as far as I know only the calico is domiant for female, the male is rare and sterile

No, but almost all calico cats are female. Here is why most calico cats are female, but if you read carefully, you will understand that it is pretty much a 50/50 chance of them being any other color:
As difficult as it might be to believe, it is true. In order to understand why, here's a quick lesson in genetics: The genes that control feline coat color are found on the X chromosome. Females have two X chromosomes; males have an X and a much smaller Y. (During fertilization, the female contributes an X to the embryo, whereas the male contributes either an X or Y. If it is an X chromosome, the embryo is female; if it's the Y, the result is a male kitten.) To compensate for this imbalance, part of one of the female's X chromosomes, on which the genes for orange, black and white coat color are coded, is inactivated or turned off. Inactivation takes place several days after fertilization when the embryo has grown from a single cell to a cluster of cells. It is a random act as to which X chromosome is inactivated in each cell. In some cases, it might be the gene for white coat color; in other cases, it will be black. This random turning off of genes results in the unique patterning of the calico and tortoiseshell cat.
It is a rare genetic occurrence, but a male calico can result. This cat will have two X chromosomes and a Y chromosome, and will usually be sterile.

The black coloring is not affected or determined by the sex chromosomes determining gender. Most tortoiseshell and calicos are female as it is a recessive gene and it takes two X chromsomes to get the orange color. With orange tabbies there is a statistically probability (75%) the cat will be male, 25% will be female. You can still get a litter of female orange kittens just like people can have four girls and no boys, or all boys and no girls.

No . There just as many male black cats as female. All of the black cats that I knew were all Male.

NOOO!!! I have owned 5 black male cats personally and only 1 female black one. My brother currently has a solid black male cat.

Interesting question, but I haven't heard of this before....I have a male black cat now, but I had a female when I was a kid.

There are as many male black cats as there are female.

No, I think that it is 50/50. Accually I know. I have 2 black cats that are male. One is full black and one has a white stripe on his neck.

No! Not all black cats are female. I had one that was pure black and male.
