Are blue eyes a strong gene?

Are blue eyes dominant or recessive?

Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.

Are blue eyes a weak gene?

Blue eyed people have a weak HERC2 enhancer and so have a lazy OCA2 gene. This makes perfect sense considering how eye color works and what the OCA2 gene does. OCA2 is one of the genes responsible for making pigment in the body. The stronger the OCA2 gene, the more pigment you make.
