Do I carry a recessive blue eye gene?
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.
What are the chances of having a baby with blue eyes?
Predicting Eye Color
| Probability of Eye Color | ||
|---|---|---|
| Parent 1 | Parent 2 | Brown |
| Blue | Blue | 0\% |
| Blue | Green | 0\% |
| Blue | Brown | 50\% |
Can green and brown eyes make blue?
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.
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.
Is blue eye color dominant or recessive?
Two Pairs of Recessive Genes When both parents have blue eyes, as shown here, they will both have a pair of recessive genes for blue eye color. All of the children will therefore have blue eyes since there is no dominant gene present to mask the recessive gene.
Are blue eyes a sign of inbreeding?
Does blue eyes come from inbreeding? New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today. What are signs of inbreeding?
How can I find out if my baby will have blue eyes?
Look at your family background first. People with blue eyes usually have European ancestry. If either you, your partner, or anyone in your direct or second line of heredity (parents, grandparents, siblings, or aunts and uncles) has blue eyes, there is a chance that your baby could.
