What do two blue eyed parents make?
Eye colour is a polygenic trait; it is determined by multiple genes and the interactions between them. This is what makes it possible for two blue-eyed parents to have brown-eyed children. There is evidence that up to 16 genes can influence eye colour; the two most important genes are OCA2 and HERC2.
What are the chances of having a blue eyed baby if both parents have blue eyes?
Predicting Eye Color
| Probability of Eye Color | ||
|---|---|---|
| Parent 1 | Parent 2 | Blue |
| Blue | Blue | 99% |
| Blue | Green | 50% |
| Blue | Brown | 50% |
Can 2 blue eyed parents produce hazel eyes?
For example, we now know it’s possible for two blue-eyed parents to have a child with brown eyes — something the old model of eye color inheritance would have deemed impossible. Many white, non-Hispanic babies are born with blue eyes and then develop brown, green or hazel eyes in childhood.
Can 2 blue eyed parents have a green eyed child?
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…
Can a blue eyed parent have a brown eyed child?
A common myth is that parents who both have blue eyes cannot have a child with brown eyes because of dominant and recessive genes, but in reality genetic variations sometimes produce unexpected results. Though there is a less than 1% chance of blue-eyed parents having a brown-eyed child, it is not out of the question.
What are the chances my baby will have blue eyes?
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.
Can a hazel eyed child have blue eyes?
Two hazel-eyed parents are likely to have a hazel-eyed child, although a different eye color could emerge. If one of the grandparents has blue eyes, the odds of having a baby with blue eyes increases slightly. If one parent has brown eyes and the other has blue eyes, the chances of having a brown-eyed or blue-eyed baby are roughly even.
Which is more likely to have brown or blue eyes?
Two brown-eyed parents are more likely to have a child with brown eyes. If one of the grandparents has blue eyes, the chances of having a blue-eyed baby increase slightly. If one parent has brown eyes and the other has blue eyes, eye color is more of a toss up.
