Can a brown eyed parent and a blue eyed parent have a blue eyed child?

So, to try and clarify things, let’s think about this situation. 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.

What are the chances of having blue eyes if one parent has brown?

If both of you have brown eyes, then there is generally a 25\% chance that the baby will have blue eyes if both of you carry the recessive blue-eye gene. But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1\% chance of the baby having blue eyes.

How can parents with brown eyes produce an offspring with blue eyes?

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.

Do brown eyes overpower Blue eyes?

The brown-eye gene is dominant and overrides the blue-eye gene, so all the children have brown eyes. However, if the father also carries a blue-eye gene and a child inherits one from each parent, that child will have blue eyes.

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 green and brown eyes make blue?

Because of this, it is possible for both green and brown eyed parents to be carriers for blue eyes. And as carriers, they each can pass down blue eye genes to their children. Let’s go into a bit more detail about how all of this works.

Are brown eyes always dominant over blue eyes?

They suggested that brown eye color is always dominant over blue eye color. This would mean that two blue-eyed parents would always produce blue-eyed children, never ones with brown eyes. For most of the past 100 years, this version of eye color genetics has been taught in classrooms around the world.

Are blue-eye genes dominant or recessive?

In this example one parent has blue eyes and one has brown eyes. The mother carries two blue-eye genes, so her eyes are blue. The father carries two brown-eye genes, so his eyes are brown. Brown-eye genes are dominant. This means they override blue-eye genes. The mother has two blue-eye genes and passes on a blue-eye gene to each of her children.

What are the chances of having a blue-eye baby with brown eyes?

If both of you have brown eyes, then there is generally a 25\% chance that the baby will have blue eyes if both of you carry the recessive blue-eye gene. But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1\% chance of the baby having blue eyes.

What is the dominant eye color in a child?

The brown-eye gene is dominant and overrides the blue-eye gene, so all the children have brown eyes. However, if the father also carries a blue-eye gene and a child inherits one from each parent, that child will have blue eyes. Human Body › Your amazing body › Why are my eyes brown?
