Why are male tortoise-shell cats so rare?
Tortoiseshell cats are almost always female because the genes that determine coat color are located on the X chromosome. Females have two X chromosomes, while males have only one. This means that in order for a male cat to be tortoiseshell, he must have two copies of the tortoiseshell gene, one on each X chromosome. This is a very rare occurrence.
