Multicolored, Calico cats are the product of multiple fathers. Is it possible for a human child to have more than two parents? Researchers have discovered that it may be possible for children to have one father, but two mothers. This would make us less likely to inherit diseases, most of which come from the mother’s (mitochondrial) DNA.
A mother’s genetic contribution to her child comes in two separable parts. The largest is the 23 chromosomes in the nucleus of an unfertilized egg. The father also contributes 23 chromosomes in the sperm that fertilizes the egg.
