Can two people with blue eyes have a brown eyed baby?
Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child. Genetics is so much fun! … Two of the most important genes in eye color are OCA2 and HERC2.
Do both parents need blue eyes to have a blue eyed child?
