No, the eyes will not be green, nor will one eye be one colour and the other eye another.

Seeing as how blue eyes is recessive, yellow eyes would probably be dominant as a new type of pigment.

It would be cool if the child's eyes turned out green. Guess you'll have to find a person with yellow eyes to experiment with. ;)

Eye color is what is considered to be multifactorial inheritance. There may also be incomplete penetrance of genes that are passed on. Therefore, if one person has hazel eyes (what you are calling yellow) and one has blue, then both of these are relatively non-pigmented, and the safest bet would be EITHER blue or hazel occurring in offspring, although if either of the grandparents or greatgrandparents have brown eyes these can manifest as well! It is very unlikely and uncommon to have one eye one color and another eye a different color. This is usually a developmental anomaly....both eyes are genetically programmed for the same appearance in most cases. It is NOT straight mendelian inheritance as in the example of flower color, or fruitfly wings! Hope this helps.

To try to answer the intent of your question (I too have never heard of yellow-eyed people) ... eye color in humans is what is called a multi-allelic trait, meaning that the genes for color have more than one allele - there is not just one gene for blue & therefore one kind of blue eyes everybody has. (same for hair as well) So two blue eye-parents may not have a green-eyed kid. They could - it depends on any recessive genes hanging around.

To further complicate this issue, there is such thing as partial dominance.Two brown eyed parents with recessive (therefore unexpressed) genes (alleles) for blue eyes may have a green-eyed kid (if brown + blue = green, which I am not sure it does this is only a theoretical example)

Most people, however have eyes that more or less match each other, whatever color they are. That matching is called billateral symetry.

If someone actually has yellow eyes, it's possible I suppose, though if you're just thinking about colors mixing, I would say no. Like the other individual said, we don't know the dominance of yellow (again, if there was such a thing). It would probably be like blue, recessive, so one blue gene and one yellow gene do sound like they would produce green or just some odd looking blue.

Theoretically, the genes in question would be Yellow Eye genes and Blue Eye genes. But they are not like paint or light, they do not mix together, it's either one of the other so which ever one is more dominant would write over the other one.

Umm, no...thats not how genetics works! Many people have green eyes, but there aren't yellow eyed people walking around! Basically, there are dominant and recessive genes. So, mom has blue eyes (recessive gene) and dad has brown eyes (dominant gene), chances are the child will have brown eyes. (I can't remember the percentage/ chances).

Check out Gregor Mendel's work. He should be in any basic bio book.

Eye colour is polygenic, meaning that many genes administration the quantity of pigment interior the iris. Brown has the main pigment, observed by ability of mild brown, hazel, eco-friendly, gray, and blue, with the smallest volume of pigment. Brown eyes are dominant to blue eyes; in spite of the undeniable fact that, somebody with brown eyes ought to hold recessive characteristics for eco-friendly or maybe blue eyes. considering that recessive characteristics are hidden by ability of dominant characteristics (they don't tutor), a brown-eyed couple ought to hold the hidden genes and supply beginning to a blue-eyed infant with out the intervention of a milkman. merely like a brown-haired couple might have redheads and blondes. it would be greater probable for them to have brown-haired toddlers, in spite of the undeniable fact that that is quite accessible and not uncommon to have toddlers with diverse hair/eye colorations. on the different hand, once you're staring at mom and dad exhibiting recessive characteristics, that's probable their infant could have the recessive characteristics. that's with the help of the fact the recessive characteristics in hassle-free terms look if there are not any dominant characteristics to conceal them. subsequently, if the two mom and dad have blue eyes, the child will greater advantageous than probable have blue eyes. If the two mom and dad have purple hair, the child will probable have purple hair. i desire this permits and is not too confusing.

No. The eye colour will be either blue or yellow (I've never seen yellow eyes!) and definitley not green.
Duh!

I don't know about the genetic dominance issues of a yellow eyed person, because I have never heard of such a person. Are you talking about human beings?

You will not get green eyes. With DNA there is not a mixing of the two resulting in some variation of both. You get one or the other.
