Can 2 blue eyed people have a brown eyed child?

Can 2 blue eyed people 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.

Can two parents with blue eyes have a child with any other eye color?

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.

Do all siblings have the same eye color?

Siblings can inherit various genes from their parents, and they don’t always get the same ones. That’s how you’re able to get one sibling with light blue eyes versus another sibling who has dark brown-colored eyes.

What are the chances of having a brown eyed child?

Filling in the first one immediately gives a brown eyed child: Here are the rest of the possibilities: Each child has a 25\% chance of having brown eyes and a 75\% chance of having blue eyes. This is simplified since the other eye color genes (like those that influence green eyes) are being ignored.

What are the chances of having a blue eyed child?

Each child has a 25\% chance of having brown eyes and a 75\% chance of having blue eyes. This is simplified since the other eye color genes (like those that influence green eyes) are being ignored. But it does mean that brown (or green or hazel or…) eyes are a definite possibility for these blue eyed parents.

What determines whether or not you will have green or blue eyes?

The first gene determines whether or not you will have brown eyes. If it says have brown, then the other gene doesn’t matter. You will have brown eyes. If it says not to have brown eyes, then the second gene kicks in. This gene will determine whether you will have green or blue eyes.

Are brown eyes dominant or recessive?

Firstly Brown eyes are dominant and blue eyes recessive. Your father has two genes for eye colour. If they are both for Brown eyes, then you and your siblings will all have brown eyes. If your father has a brown and a blue gene, he will have brown eyes, but you and your siblings can have either blue or brown eyes.
