Can two people with brown eyes give birth to a blue-eyed baby?
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.
How can two parents with brown eyes produce an offspring with blue eyes?
The gey gene has one allele that gives rise to green eyes and one allele that gives rise to blue eyes. The bey2 gene has one allele for brown eyes and one for blue eyes. … For example, if two parents with brown eyes each passed on a pair of blue alleles to their offspring, then the child would be born with blue eyes.
How is it possible for 2 brown-eyed parents to have a blue-eyed child brown eyes are the dominant trait?
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 two people with brown eyes have a blue-eyed baby class 10?
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.
Can 2 brown eyes make a green eyed baby?
Two blue-eyed parents are likely to have a blue-eyed child, but it’s not guaranteed. Two brown-eyed parents are likely to have a brown-eyed child. Again, it’s not guaranteed. Two green-eyed parents are likely to have a green-eyed child, although there are exceptions.
Can 2 brown eyes make hazel eyed baby?
Not really. Two brown-eyed parents are likely to have a brown-eyed child, but could potentially have a child with blue, green or hazel eyes, depending on the combination of genes from each parent.
Can you really have violet eyes?
Violet is an actual but rare eye color that is a form of blue eyes. It requires a very specific type of structure to the iris to produce the type of light scattering of melanin pigment to create the violet appearance.
Are blue eyes green recessive?
Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.
