Are Calicos always girls?Genders are revealed! Calico-girl (obviously), black and white-girl, orange and white-boy
It's rare for a calico to be male.
Thanks!The gene required for calico is on the X Chromosome and in order for calico to be present, 2 X genes are required. Since boys are XY, the only way a male can be calico is if the mother carries a double copy of the X and passes that gene to her son, which is extremely rare.
