What chooses what eye color is? Besides genes and stuff, what causes eyes to be a certain color?

mostly from ur dad side of the family and the mom side of the family there are dominant traits in your DNA and recessive. look at ur family member if they have a certain color than that is the dominant trait and if one person has a different color that is also a chance because that is the recessive.

It is "genes and stuff". Lol, so it depends on your parents. If one of your parents has a homozygous dominant gene, your eyes will be that color. If both of your parents have homozygous recessive, your eyes will be that color. If both homozygous (homo means same) dominant will always win out. If its heterozygous, thats when porbabillty will come into play. Heres a website that will explain it for you: http://homepages.ius.edu/GKIRCHNE/Mendel.htm
It gets kind of confusing, but thats the best I could explain it. The human body is very complex in the way it works and how it becomes what it is. I hope I helped!

Eye color or eye colour is a polygenic trait and is determined primarily by the amount and type of pigments present in the eye's iris. Humans and other animals have many phenotypic variations in eye color. In humans, these variations in color are attributed to varying ratios of the two types of melanin produced by melanocytes in the iris: eumelanin and pheomelanin. The brightly colored eyes of many bird species are largely determined by other pigments, such as pteridines, purines, and carotenoids.
Three main elements within the iris contribute to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma. In eyes of all colors, the iris pigment epithelium contains the black pigment, eumelanin. Color variations among different irises are typically attributed to the melanin content within the iris stroma. The density of cells within the stroma affects how much light is absorbed by the underlying pigment epithelium.

Dominant traits in your DNA. Different colors are dominant, and others are recessive.
