How a father with brown eyes and a mother with blue eyes can have children with either brown or 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.

What happens when one parent has brown eyes and the other blue?

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 hazel eyed father and a blue eyed mother have a brown eyed child?

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.

Can parents with blue and brown eyes have a blue-eyed baby?

To find any recessive traits, it’s helpful to know the grandparents’ eye colors. For example, a blue-eyed parent whose entire family has blue eyes and a brown-eyed parent whose mother and father were brown- and blue-eyed has a 50/50 chance of having a blue-eyed or brown-eyed child.

Can 2 blue-eyed parents make brown?

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 happens when a brown eyed man marries a blue eyed woman?

A brown eyed man whose mother was blue-eyed marries a blue-eyed woman. The children shall be When a brown eyed heterozygous male marries a homozygous blue eyed woman, in the next generation, 50\% children are brown eyed and 50\% children are blue eyed are formed.

What is the phenotype of a man with a blue eyed mother?

The man had a blue eyed mother (bb); thus phenotype of the man is “Bb” as he has received one “b” allele from the blue eyed mother. The expected children of a marriage between the blue eyed woman (bb) and a brown eyed man (Bb): Children = 1 Blue : 1 Brown.

Is blue eye colour dominant or recessive?

Blue eye colour is recessive to brown eye colour. A brown eyed man whose mother was blue – eyed marries a blue – eyed woman. The children shall be Blue eye colour is recessive to brown eye colour. A brown eyed man whose mother was blue-eyed marries a blue-eyed woman. The children shall be

What is the ratio of Brown Eyed to blue eyed children?

When a brown eyed heterozygous male marries a homozygous blue eyed woman, in the next generation, 50\% children are brown eyed and 50\% children are blue eyed are formed. The ratio of brown eyed to blue eyed children is 1:1. It is called test cross.
