what is the statistical probability that two blue eyed parents can have a brown eyed child? (birth child)?

Answer 1

it is very rare, but possible.. normally 2 blue eyed parents produce a blue eyed child.

The gene for blue eyes tends to be what's known as recessive - it's weaker or overshadowed by the brown eye gene. In general, a child will only have blue eyes if both of their eye colour genes are blue (however, in reality there may be exceptions).

Answer 2

Nope. the two blue eyed mothers and fathers can not have any brown eyed toddlers. even nonetheless there's a element referred to as co-dominant genes, seem it up. I dont rather need to get into severe element, yet many situations the two blue eyed mothers and fathers could have eco-friendly eyed toddlers, to simplify, eco-friendly eyes are comparable to blue. Eye shade genes are actually not black and white sure or no so some distance as genetic donation like human beings think of. eye shade is because of a repeated development of "make blue eye pigment" in you genes somebody with blue eyes would have an exceptionally solid encoding for blue with say 27 repeats on gene A and 24 repeats on gene B, someon else would have vulnerable encoding including 12 blues and sixteen blues on A and B. The vulnerable encoded is probable to surely have eco-friendly eyes. Say this each and every determine has a million solid a million vulnerable encoding 12 and 26, and the different has 15 and 24. you success out and get 12 and 15 your eco-friendly

Answer 3

Eye color isn't as simple as blue being recessive and brown being dominant. In reality it is a mix of many different genes that determine eye color. If direct family members such as parents and grandparents have all the same color of eyes, then kids could end up with that color or something different. Blue and brown could make hazel or green or blue green or light brown, maybe even dark brown depending on the genes that are carried by the parents and then expressed.

Answer 4

In Zoology class, I did genetic charts. Blue is recessive, while brown is dominant in eye color. It is considered impossible for two blue-eyed parents to have a brown-eyed child. The blue-eyed people carry only the gene for blue eyes, else they would be brown-eyed. If a couple with blue eyes has a child with brown eyes, the mother had a secret lover with brown eyes. A brown-eyed person may carry the gene for blue eyes. I cannot do the charts here to show you what we did in Zoology...so please take my word for it.

Answer 5

Very good, considering that the blue eyed gene is recessive and brown eye color is the dominant. Even though you both have blue eyes, brown is bound to come out in the wash.

Answer 6

What color are the grandparents eyes? The more blue eyed grandparents the better the chances.
Does it really matter?

Answer 7

The brown trait is dominant over blue trait. It does happen but it is a small ratio. 3 Chromosones are known that determine eye color. Scientists know more chromosones are involved in eye color. Scientists cannot explain gray or hazel eyes either.

Answer 8

It depends on the actual genes each parent has and how much of the gene for each eye color has. Your kid could end up with green eyes!!

Answer 9

it has half chance o bcomin either blue eyed r brown

Answer 10

I think it depends on a population, because this sign is not as simple as it may look.
