HOw is the eye color of a child known, and what different shades of eye color are there..

Someone (hopefully a medically trained someone) looks at it.

There are tiny imps that live in your eyeballs and they look out and see things around you. Then they scribble a quick little drawing down on a material we can absorb into our "receivers" and they press it against them. We then generate the object they've drawn in our minds. Some people have more artistic imps than others.



Oh wait... eye color... well it depends on your imps sense of fashion. Whatever drapes they choose to hang up. Hence why some peoples eye colors seem to change.

But how do the imps see? Tiny people?

Peace
different combinations of dormant and active alleles (groups of codons in the DNA) determine what pigments are made in the iris
not sure what the different shades are

too tired for any funniness...

Intelligent Design answers, "God decides your eye color, based on His personal preferences and His great universal plans."

If you want to listen to those nutty "scientist" explanations instead, do so at your own peril!

i don't understand it so it must be wrong!! ;)

(of course this could be applied to the hardcore evolutionist mob, in the interests of fairness...)

A person's eye color is determined by both parents. This is basically a genetics question. Brown eyes are dominant, blue and green are recessive. they are poly genes related as well. One person could have copies for two eye colors so Jane Doe has brown eyes so she would at least have one copy of a brown eye gene but she could also carry a blue eye gene as well..and when she has a child with John Brown who has blue eyes (( he has to have 2 copies of the blue eye gene for him to have the blue eyes)) she could have a blue eyed child as well as a brown eyed child. Dominant genes only require one copy of the gene for it to be expressed.

Figure this out for me please: my mother has blue eyes, so she can only have two copies of the blue eye gene. My father has dark brown eyes, and HIS mother has blue eyes, so she gave him a blue eye gene and his father must therefore have given him the dark brown eye gene in order for him to have dark brown eyes. Therefore my mother gave me a blue eye gene, and my father gave me either a blue eye gene (in which case I would have blue eyes) or his dark brown eye gene. How did I get green eyes? And before you suggest the milkman had green eyes, let me assure you I look identical to my father in all respects but eye colour.

I dunno, it sounds more like you should have hazel eyes as opposed to green anyway...

They were blue at birth (like all babies), then turned dark dark brown, then turned to hazel in elementary school, and by graduation they were green and have remained so.

Edit: "all babies" should probably read "most caucasian babies". Anyway I should have read the linked article first, I see there are at least three different sets of eye colour genes and the placement of dominant and recessive gene combinations on the three locations changes the expression of the alleles.

I`ll cut to che chase of why i asked this, ny eues, strange to say, change from hazel/greenish to brown in the summer winter rotation..
But i know they are okey, I have 20/20 vison
Thanks for the info ppl :)
and what eye color can my childran have, i have the eyes described above, and am other wise a 176cm tall caucasion with dark-brown hair..
My mother has broen eyes and my father green, can my childran have blue, or are they destened to have brown couse of the geen dominant thingy

It's not an especially rare condition although the more common switch is from blue to green/hazel instead of green/hazel to brown, not common but not all that strange. Other factors can be responsible for eyes which change color, but in your case with the seasonal link it is most likely pigment levels in response to light exposure (tanning). Nothing really strange about it, just something that happens in some people and not in others. There seems to be an age link in many people, and you may find you eye color "settling down" and the differences becoming less distinct as you become older, which is nothing to worry about if it does happen and nothing to worry about if it doesn't.

There were years ago 4 genes known to affect eye color and may be more now, so a simple dominant-recesssive matching doesn't work. Assuming eye color were controled by a single gene, it is possible that you have one blue eye gene and one green/brown gene (cannot say what the chance of that is though without knowing the genotypes of your parents or the phenotypes going back further), and thus if it did and your partner were blue eyed your children would have a 50% chance of having blue eyes. However it's not that simple because there are multiple genes, and further there may be enviromental factors in how those genes are expressed (or may not, hard to be sure because people get upset when you take kids, put them in a cage and feed them chemicals to test ideas like this).

To avoid giving you an explaination of eye color and genetics which may be completely wrong (darn human rights activist keeping people from testing these ideas) I'll give you a short form: No, your children are not destined to have green or brown eyes. Find a blue eyed mate for the best chances of having blue eyed children and recognize that you even with a blue eyed mate you are more likely to have brown or green eyed children. If the eye color of your children is not the sole factor in your selection of a mate and you mate with a brown or green eyed person, recognize that a blue eyed child is unlikely but not impossible.

AFAIK green eye gene is the blue eye gene mutated slightly.

This might sound odd but I dont know what my eye color is, and nor does anyone else I know. The most common description I get is "You have bluey, greeny, browny, yellowish, greyish eyes". I go with "blue" but then people say "no you dont" and i say "what color do i have?" and they look, then stare, then look confused and then say the "bluey, greeny, browny...." thing.

I kinda have the same. Mine are mostly green though, but there's also some brown, blue and/or grey at times

I have a ring of brown around the iris, a ring of yelowish green further out, and a ring of blue further out again. Light green flecks are peppered throughout.

They also change colour/hue with the seasons.

I had a girlfriend like that once... and let me tell you that can be a pain. I can't count the number of times I got smacked for "not knowing what color her eyes were"..... BUT SHE COULDN'T TELL ME WHAT COLOR THEY WERE EITHER!!!!

....hmm....maybe thats more on account of my dating psychotic *@^#%@! than eye color....
