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.
What are the odds of two blue-eyed parents having a brown-eyed child?
To find any recessive traits, it’s helpful to know the grandparents’ eye colors. For example, a blue-eyed parent whose entire family has blue eyes and a brown-eyed parent whose mother and father were brown- and blue-eyed has
a 50/50 chance
of having a blue-eyed or brown-eyed child.
Can two blue eyed parents have a brown eyed child?
Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes
it possible for two blue-eyed parents to have brown-eyed children
.
