With high levels of brown melanin, the eyes look brown..
What do daughters inherit from their fathers?
Girls get two X chromosomes, one from Mom and one from Dad. This means that your daughter will inherit X-linked genes from her father as well as her mother. When your daughter inevitably ends up with his X chromosome, does that mean she’ll inherit all of his X-linked genes and traits? Genes, yes.
Do both parents need blue eyes to have a blue eyed child?
If both parents have blue eyes, the children will have blue eyes. If both parents have brown eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
Can a brown eyed father and blue eyed mother 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.
Can parents with brown eyes have a blue eyed child?
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 + blue eyes = 50% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene.
