What are the chances of two blue eyed parents having a brown-eyed child?
OCA2 and HERC2 are Linked Imagine these parents: If we assume the OCA2 and HERC2 genes were far from each other, we’d get the following Punnett square: The results are a 9 in 16 chance for brown and a 7 in 16 chance for blue. This assumes that any of four combinations of the two genes is possible.
Can a brown-eyed and blue eyed couple have a green eyed child?
First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. An increasing proportion of the yellow melanin, in combination with the black melanin, results in shades of colors between brown and blue, including green and hazel.
Can a brown-eyed and blue eyed couple have 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.
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.
What eye color is the rarest?
Green is the rarest eye color of the more common colors. Outside of a few exceptions, nearly everyone has eyes that are brown, blue, green or somewhere in between. Other colors like gray or hazel are less common. Once upon a time, every human in existence had brown eyes.
What is the 2 rarest eye color?
Green is the rarest eye color of the more common colors. Outside of a few exceptions, nearly everyone has eyes that are brown, blue, green or somewhere in between. Other colors like gray or hazel are less common.
What’s the prettiest eye color?

Can you have purple eyes?
Share on Pinterest A person cannot be born with purple eyes, and Alexandria’s genesis is not a real condition. Most babies are born with brown eyes. However, many of Caucasian heritage initially have blue or gray eyes. This color may darken over time, to become green, hazel, or brown.
Can two brown eyes parents produce blue eyes child?
Two brown eyed parents could be carriers of the recessive gene that causes blue eyes . This is because brown eyes are only an indication of the presence of the dominant gene. This gene will still manifest its traits in the presence of a recessive gene, which in this case is the blue-eyed gene.
Can a blue eyed father have a brown eyed child?
A common myth is that parents who both have blue eyes cannot have a child with brown eyes because of dominant and recessive genes, but in reality genetic variations sometimes produce unexpected results. Though there is a less than 1% chance of blue-eyed parents having a brown-eyed child, it is not out of the question.
Can brown eye person come from blue and green parents?
What we are taught in high school biology is generally true, brown eye genes are dominant over green eye genes which are both dominant over blue eye genes. However, because many genes are required to make each of the yellow and black pigments, there is a way called genetic compensation to get brown or green eyes from blue-eyed parents.
Can 2 Brown Eyed People have a green eyed child?
The University of Delaware suggests that it is possible for two green-eyed parents to have a child with brown eyes. As Science Daily reports, the polygenic nature of eye color genetics is the reason why almost any parent-child combination of eye colors can occur.
