Polydactyly is a genetic condition that affects the feet and hands of people and animals. It causes the person or animal to have extra toes or fingers. I was born with it in my feet, having 6 toes on each foot.
Polydactyly is more common in men, because it is a genetic disorder. Because females have 2 X chromosomes, a recessive trait passed down on one will be covered by the dominant trait on their other X chromosome for no polydactyly. Males though, have an X and Y chromosome which means that that the Y chromosome, carrying no trait for polydactyly, will not affect an X chromosome with the allele for polydactyly. Hence, polydactyly is found in men more than women.
