Most calico cat's are girls (although there are few sterile male), so does that mean calico manxes are mostly female as well?
A true Calico is female. The more familiar name is Tortoiseshell.
Calico cats are female because it requires 2 x chromosomes to get all three colors. The males only get 1 x chromosome so they only get 2 colors (tortoiseshell).
The color of a manx mix would depend on whether it's male or female, and which chromosome copies it received from its parents.
So it's the sex that determines the color, not the color that determines the sex.
Calico cats are nearly always female regardless of breed. The reason is that both the orange gene and the black gene are found in the same location on the X chromosome. They are codominant, so if both genes are present both are expressed. For both colors to be present in the same cat the cat has to have one X chromosome with the gene for orange and one X chromosome with the gene for black. In genetic notation it looks like this: Xo Xb. By definition any cat with two X chromosomes is a female, except in the rare case of an XXY male. Such males are feminized in appearance and sterile due to nonmotile sperm that are low in count . The white spotting pattern is inherited separately and is not found on the X chromsome, so it is not sex linked. Without white markings the cat would be called a tortoiseshell.
Calico is a coloration, that is from genetics. Due to the X and Y chromosomes, and color, the only way a male comes about is a XXY, or, in simple terms, a mutation.

Color is a sex linked trait, through the X chromosome. So a tri color cat is XX. That means female, regardless of breed.
Uh .... I think Calico is just a coloration pattern
EDIT: Oh interesting I see they are linked cos of the chromosome .... hmmm I guess yes> _>
Yes it is the same.
I have only heard of one intact male calico that wasn't sterile.
Yes
