In real life, only some cats in three color cat may become male cats due to gene mutation, but this possibility is generally very small.
Three color cat we meet in our life is generally a female cat, which has a lot to do with the cat's genetic inheritance. Like us, the sex of a cat is determined by XY and chromosome, the female cat is XX and the male cat is XY chromosome. White is the background color and exists on the autosome.
Black and yellow are determined by the genes on the X chromosome. In this case, if the two X chromosomes of the female cat have black and yellow genes respectively, they will selectively express black and yellow when expressing, and then add the white background color of the autosome to present three colors.
Male cats have only one X chromosome, so no matter the gene mutation, they can only have two colors at most. The sex chromosome has only one color, plus the white background color on the autosome, so the average male cat has only two colors.
