In tortoiseshell cats, they can be male due to something known as Klinefelter syndrome. Although orange tabby cats may be female, the vast majority will be male. This is a similar explanation for why most orange tabby cats are male. Since male chromosomes are genetically XY, this means that it is almost impossible for them to present black and orange with white.
Since females have XX chromosomes, they can be tricolor because they can have black on one X and orange on the other X. The colors of black and orange cat fur are related to the X chromosome. The white color of the fur of cats is independent of the sex chromosomes, given by the S gene. This is a genetic condition that results from the transmission of sex chromosomes.
