How come green eyed couples often have dark eyed children, shouldn't it be the same as it is with blue eyes?

Biology 101, if both parents have two recesive genes for one specific caracteristic, then the offsprings must also be recesive, for there is no other opcion. So, when two blue eyed people get together, they're children are born with blue eyes. But, some dark eyed kids hace green eyed parents (both of them). Question is, if green eyes are recesive just like blue ones are, then why don't they behave the same way?How come green eyed couples often have dark eyed children, shouldn't it be the same as it is with blue eyes?
Well eye color is a little more of a complex phenotype than most others. Eye color is sort of an incomplete dominance. Which means that if parents have different colored eyes, most of the time the eyes of their kids will be in the middle of their eye colors. So for a person to inherit their eye color, the parents must give their genetic information. With green eyed parents, this means that they carry the gene for lighter, blue eyes, and the darker brown eyes. Because more than likely one of their parents had brown eyes, and the other had lighter blue eyes. So when they were born they had a mixture of colors. So now the people born with green eyes have the gene for dark eyes, and the other gene for light eyes. So, they can give their kid the gene for dark or light eyes, and the other parent, also having green eyes, can do the same. So if the two green-eyed people have kids, the kid will get either two dark eyed genes, one dark eyed gene, and one light eyed gene, or two light eyed genes. And because dark eyed genes are dominant to light eyed genes (meaning that in the presence of both genes the dominant one is expressed), the dark eyes are more predominantly expressed, or they may also have a sort of green hazel eye.How come green eyed couples often have dark eyed children, shouldn't it be the same as it is with blue eyes?
Well I got his one email on myspace and it said because of your genes or something.
becuase eye color is not controlled by just one gene. The same is true for hair color by the way. There are plenty of traits out there where the simplistic recessive/dominant 1:2:1 genotypes play out, for example whether or not you'll have a widows peak or shape of one's thumb. But there are many other types of inheritance such as 9:4:3:3:1 genotype ratios which take into account two genes (this is seen in skin color of pigs). Eye color is controlled by even more genes than that so that is the reason why green eye inheritance doesn't behave in the simplistic why that we all get taught about blue and brown eyes in school. It's just easier to explain it that way to kids
Sometimes a dominant trait supercedes recessive , throwing the whole probabillity chart out the window
Dunno...but i know that both my parents have brown eyes and i have blue ones lol
There has to be a dominant genotype for that particular eye color then. Then and only then a diffferent eye color is found to be present in the offspring. If each of the parents is recessive for the eye color, then the eye color of the offspring has to the same as his/her parents.
Well, even blue eyes can have a recessive gene. For example, both my parents have brown eyes. I have green eyes. My grandparents had brown and blue eyes, and no one other than my great-great grandmother in my family was rumored to have had green eyes. Everyone's is blue or brown. No matter how far back, you still hold the gene that if there is enough of that DNA present, you can be 'programmed' to have a certain eye color. It's just a matter of lesser/greater and luck possibilities. Hope that made since, I'm not too good at explaining these things in writing in such. It basically all goes back to Mendel's genetic tests. Two yellow peas flowerless could produce a green pea with flowers.
because somewhere in the family tree, someone in either the mother or father's has the different colored eyes. although the chance that it appears again is very slim, there is still the possibility that it can happen. for instance, if the parents have green eyes, but the kid has dark ones, you should proably look at the kid''s grandparent's eyes. chances are that one of their grandparents has dark eyes, or great -grandparents, and on and on.
I forgot what it's called, but there's a pigment in the irises, and brown results from a large amount and blue from a small amount. Green is in the middle. And from what I've heard, there are several genes controlling eyes... the more recessive genes, the lighter the eyes.
cuz life is retarded.. lol
My daughter has bright blues, and her father and I have dark brown eyes. I guess our recessives became prominent
try a punnent square it is a good tool for genetic probability
