Can a brown eyed and blue eyed couple 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.

What are the chances of a mother who has blue eyes and a father who is heterozygous for brown eyes to have blue eyed children?

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.

Can a kid have different colored eyes than parents?

Although nearly 75 percent of eye color is controlled by the OCA2 gene, other genes provide a pathway for melanin. These genes can raise or lower melanin levels, causing a child to have more or less melanin than either parent.

Can someone with blue eyes have a sibling with brown eyes?

Depending on what genes they get and the way that these genes are turned on or off and expressed, can play a role in eye color. That’s how you’re able to get one sibling with light blue eyes versus another sibling that has dark brown-colored eyes.

Do blue eyes come from mother or father?

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.

How do blue eyes get passed down?

How are blue eyes inherited?

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

Why does Sally have blue eyes instead of brown eyes?

So, depending on the combination of genes they received from their parents, it’s very possible that a child might not look like either parent. This explains why little Sally has her grandfather’s blue eyes instead of brown eyes like the rest of the family. It really is a genetic lottery of sorts.

How did you end up with a child with blue eyes?

This is almost certainly how the two of you ended up with a child with blue eyes. You and your husband both have blue and at least one of you has green eyes hiding behind your brown.
