Will two blue eyed parents always 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.

Can 2 blue eyed parents produce a brown eyed child?

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.

What are the odds of two blue eyed parents having a blue eyed child?

Both parents with blue eyes: 99\% chance of baby with blue eyes, 1\% chance of baby with green eyes, 0\% chance of baby with brown eyes. Both parents with green eyes: 75\% chance of baby with green eyes, 25\% of baby with blue eyes, 0\% chance of baby with brown eyes.

Can 2 blue eyed parents produce green eyes?

First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. Eye color is not the simple decision between the brown (or green) and blue versions of a single gene. There are many genes involved and eye color ranges from brown to hazel to green to blue to…

What are the chances of having a blue eyed child?

Here are the possibilities: 1 Blue eyes + blue eyes = 100\% chance of blue eyes 2 Brown eyes + blue eyes = 50\% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene. If not,… 3 Brown eyes + brown eyes = 25\%, but only if both parents carry the blue-eyed gene. If not, the chance is 0\% More

Can two Brown-Eyed partners have a blue-eyed baby?

Therefore, two brown-eyed partners can birth a blue-eyed baby. Here are the possibilities: Brown eyes + blue eyes = 50\% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene. If not, the chance is 0\% Brown eyes + brown eyes = 25\%, but only if both parents carry the blue-eyed gene.

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 is the genetic reason for blue eyes?

A Genetic Explanation. The Genetics of Blue Eyes Blue is one of the rarest eye colors worldwide. The genetic mutation behind blue eyes actually switches off the gene that colors eyes brown and leaves them blue. Everyone with blue eyes is related to a single, common ancestor.
