Eyes color

Because eye colour is set by your DNA and blue is a submissive gene therfor its over ruled by the brown gene in BOTH cases (and in your hair and your skin colour ect). You will be a carrier of the blue eye gene so if you have sex with a man with blue eyes 1/2 of your children SHOULD have blue eyes but you cant have one of each as far as i know
CATS on the other hand CAN have one green eye and one blue eye but i dont know why

Kate Bosworth has eyes of different colors, like you're describing: http://img388.imageshack.us/img388/6344/kate2eo.jpg
I have no idea. I also remember there was an actress with purple eyes.... Was it Lizzie Taylor?
My mom's eyes are green and my dad's are blue, my irises are a mix: blue on the outside and green on the inside near the pupils. But genes for both green and blue are recessive.

It's like a birth mark or somthing.It's just on part of the eye, it seems.
It is just part of the eye, but I don't think it's the sort of thing like a birth mark. Birth marks are on skin and may come and go.
It's the way DNA works, like asguard says they should both be the same color, but there's always heterochromia. It's not as uncommon as people think.
I have green eyes and red hair. and I know someone who has a green eye and a brow one. it happens sometimes I guess. Genetic mutations
A simple punnett square will reveal the 1:2:1 ratio.
To understand this, you must first understand that in sexual reproduction(meiosis)[most animals, including humans], we have 2 alleles (possibilities) for every gene expressed [x-linked dismissed]. when these get crossed, the traits can be primarily dominant or recessive (others like co-dominance exist). Depending on the combination, the dominant will get expressed if available. If you are crossing 2 heterozygous individuals for a single gene, you will get the 1:2:1 ratio of genetic makeup. This is just probability because genes cross independently. This means that 1/4 offspring will be Dominant, Dominant, 2/4 will be dominant, recessive (expressing dominant), and the last 1/4 will be recessive, recessive.
the expression of heterozygous phenotypes in eyecolor, such as this case, would probobly be due to mutation.

Although I have has several genetics classes I'm not a geneticist but I'll try:
Eye color: Brown is dominate over blue (produced melanin ), green and gray.
Hair color: Black dominates brown (produces most eumalanin), brown dominates blond and red.
- neither hair, skin or eye color genes need be connected, though in some cases such as the freckled redheads and albinos a defect in all melanin production affects their hair, eye and skin coloration
- Genes for arms and legs and most other morphology are controlled by hox genes and are bilaterally symmetric: there is no right hand gene and left hand gene, no right eye gene and no left eye gene.
- Differing eye color in a person is caused by mosaicism, in rare cases chimaerism.
