Can a brown eyed father and blue eyed mother have a blue eyed child?
Someone with brown eyes may be carrying one blue allele and one brown allele, so a brown-eyed mother and a blue-eyed father could give birth to a blue-eyed child.
Now mix in a third green allele, which is dominant to blue, but recessive to brown..
Can you get blue eyes from great grandparents?
Yes, you have a 1 in 4 chance of carrying it, and that’s assuming that none of your other great grandparents was blue-eyed or carrying blue. Your great grandmother was homozygous for blue so each of her children *must* have been either blue-eyed or carrying blue.
Can a child have blue eyes if parents don t?
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby. … Brown eyes + brown eyes = 25%, but only if both parents carry the blue-eyed gene.
Can two parents have blue eyes?
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.
Do two blue eyed parents always have a blue eyed child?
Someone with broken OCA2 genes will have blue eyes no matter what the HERC2 genes are. … 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.
Does blue eyes skip a generation?
It might not come directly from your parents, so your odds of having blue eyes is inherently lower, but it is still quite possible. Another recessive gene that can cause a trait to skip a generation is hair colour or texture.
What is the second rarest eye color?

Can two 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. … If you have no melanin in the front part of your iris, you have blue eyes.
What are the chances of having a baby with blue eyes?
Then, it is possible that the parents will pass along the genetic information needed for blue eyes. Meanwhile, if one parent has brown eyes and one parent has blue eyes, there is about a 50/50 chance, the child will have blue eyes.
Which parent determines eye color?
The chromosomes a child inherits carry genetic information that determines eye color. Differences in the copies received from each parent causes variations in the amount of melanin produced. A region on chromosome 15 has a big part in determining eye color. The OCA2 and HERC2 genes are located in this region.
Are humans born with blue eyes?
Eye color isn’t set in stone until age 2. While only 1 in 5 Caucasian adults have blue eyes in the United States, most are born blue-eyed. Their irises change from blue to hazel or brown during infancy.
Can blue eyes skip 2 generations?
This is because you each only have blue versions to pass on to your children. That means that your kids will most likely all have blue eyes. So once dominant traits like dark eyes aren’t passed on to the next generation, they can be “lost.” Well, it pretty much looks impossible for your kids to get your parents’ eyes.
Are blue eyes the rarest?
Between 8 and 10 percent of people worldwide have blue eyes. Blue eyes are most common in Europe, especially Scandinavia. People with blue eyes have the same genetic mutation that causes eyes to produce less melanin. The mutation first appeared in a person living in Europe about 10,000 years ago.
Do babies get their eye color from Mom or Dad?
In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby’s eye color is determined by the parents’ eye color and whether the parents’ genes are dominant genes or recessive genes.
Is blue eyes dominant or recessive?
The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive. If both parents have brown eyes yet carry the allele for blue eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes.
