Question

1.) what is the genotype of most male calico cats?

2.) How is the MT-DN1 gene maintained in the mitochondria during the cloning process?

Answer 1

1. Male calico and male tortoiseshell are abnormal. This is because males have only single copy of X chromosome and therefore can have either orange or black colour as their fur colour.

But if nondisjunction of chromosomes occurs during anaphase 1 of meiosis 1 in the formation of the gametes in a tortoise shell female parent, then it will result in the formation of a male calico.
