Can parents without blue eyes have a blue eyed child?
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 is the rarest eye color in the world?

Can two green eyed parents have a blue eyed child?
A lot. A brown eyed dad and a green eyed mom can have a blue eyed child because there are at least two eye color genes. Because of this, it is possible for both green and brown eyed parents to be carriers for blue eyes. And as carriers, they each can pass down blue eye genes to their children.
Are all blue eyed people related?

Can 2 parents with blue eyes 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.
