Do blue eyes come from mother or father?
The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
Who is most likely to have blue eyes?
Blue eyes are most common in Europe, especially Scandinavia. People with blue eyes have the same genetic mutation that causes eyes to produce less melanin. The mutation first appeared in a person living in Europe about 10,000 years ago. That individual is a common ancestor of all blue-eyed people today.
Do grandparents eye color Affect baby?
If, say, my wife was also blonde and blue-eyed, would it somehow lessen the chances of our children being blonde and blue-eyed? Yes, grandparents’ genes can affect how their grandchildren look.

Which traits skip a generation?
Recessive traits can skip generations because a dominant phenotype can be produced by either a homozygous dominant genotype or a heterozygous genotype.
