Are blue eyes recessive and brown eyes dominant?


Quick Answer

Brown eyes are generally dominant over blue eyes, but since a blue-eyed child can have brown-eyed parents, blue eyes are not a strictly recessive trait. Eye color inheritance is more complicated than simple dominant and recessive traits, according to The Tech Museum of Innovation.

Full Answer

Roughly 15 genes have been shown to influence eye color inheritance. However, Science Daily states that blue eye color is actually attributed to a single genetic mutation, and a study from the University of Copenhagen claims all people with blue eyes have a common ancestor. This theory proposes that a genetic mutation 6,000 to 10,000 years ago caused the blue-eyed anomaly.
