How do you get different color eyes?

Answer 1

A black kid can get blue eyes one of two ways, one way is through mutation and one way is by having blue eyed ancestors some distance in the distance past. A mutation occurs when a particular gene is not expressed for some reason or another. All babies are born with blue eyes. Shortly after birth, a particular gene tells most black kids, "Turn that kid's eyes a different color." Occasionally, something happens and does not turn on that particular gene. Generally, it makes no difference in eye color. With other genes in the body are not turned on, the results can be deadly and cause such diseases as cystic fibrosis. The other reason can happen because eye color is a recessive gene. If two ancestors had blue eyes, those genes might be the eye color genes that just happen to come together in that baby. If the parents had a dark and a blue eye gene, their eyes would be a dark color. The blue eye gene would not be expressed. It would be recessive. If the blue eye genes came together, then the baby's eyes would be blue. Gregor Mendel, a monk, worked out the laws of inheritance for dominant and recessive genes.

Answer 2

Two people have to have a baby who both carry the recessive blue-eyes gene. There will be a 1-in-4 chance they will have a blue-eyed baby. If a brown eyed parent carries blue eyes and the other parent shows blue eyes it will be 75% likely the child will have blue eyes. If both parents have blue eyes the child will have blue eyes 100% of the time.

Answer 3

its easy to change youe eye color. if your eyes are green, and u want to make them blue, then put on blue contacts. if your too young, ask a parent or guardian for an eye exam, and they'll see if u need contaces. later on you can pick the COLOR of the contacts, and just pick blue. i know all of this...and im just eleven...ur welcome for the information 8)

Answer 4

Someone may inherit blue eyes if the two parents give this required genes to. But blue eyes are a recessive trait, therefore, it is less common, unless both parents have a homozygous recessive trait for blue eyes, which gives you a hundred percent chance for blue eyes, but you can't control whether you give that. There are three types of trait passed on by parents: a homozygous dominant trait, a homozygous recessive trait, and a heterozygous trait. Everyone has at least one kind of these. Let's say for example B=brown eye color (dominant), and b=blue eye color (recessive). A homozygous dominant trait would look like: BB, a homozygous recessive trait would look like: bb, and a heterozygous trait would look like: Bb. Then to have the blue eyes, the child MUST have the homozygous recessive trait, because the dominant trait ALWAYS wins. The Punnett Square helps determine the percent chance of blue eyes-if you know the parents' eye traits. There is always chance that one of the parents doesn't have the blue eyes genes too. Luckily, I just learned this today in school and I've put together a tutorial-go here: http://tinypic.com/r/5afera/7. (:

Answer 5

The parents have to carry the gene for blue eyes, which is inherited by the child.

Answer 6

heterochromia is the condition that cause the iris of the eye to be diffrent on each eye.

Answer 7

You might have to get blue eye contacts if your eyes are not good, but if your eyesight is perfect, you can get the contacts with no prescription in them.

Answer 8

Blue eyes are inherited. If they don't run in the family, the baby won't get blue eyes.
