green, black, brown, blue?

Not settled after all partial genetic explaination of eye color. it's not one classic dominant/recessive allele a la the monk Mendel. three known + unknown genes involved, everybody's still beautiful.

A second gene, located on chromosome 19 (the gey gene) has a blue and a green allele

oh noes!

Years ago I dated a very beautiful young lady who just happened to have one brown and one blue eye. So much for a simple genetic explanation.

...but people with brown eyes are a bit prettier than the others.

...except thems with the steel cold baby blues.

What about one eye?

I don't know where you heard that, scarabic, but I assure you it's untrue. Trust me on this, I have a degree in science.

Parallax7d, that was beautiful. Thanks.

parallax7d, that was really great.

Eye color calculator, previously on mefi (it's fun!).

both parents brown eyes, my eyes blue. What is your relationship to your parent's eyes?

David Bowie's similar. His was the result of an injury to one eye.

Its said that the differing eye colours can often be explained in females by a process called Lyonization.
Its the same process responsible for calico cats.

It cannot explain how two blue-eyed parents can produce a brown-eyed child

For that you'll have to ask the mailman.

I got an acquaintance with blue & brown eyes. Don't think it was an injury thing.

Said by whom? That only makes sense of one of the relevant genes is on the X chromosome. On the one hand, the genes listed here are not. On the other, I don't fully understand eye color genetics, and the experts might not know that much better.

Seems like it was said by my high school biology teacher in error.
A quick search shows this page on medline, the technical term being Heterochromia.

I went to school with a girl who had one brown eye and one half-brown, half-another color (blue, I think?) eye. So wierd, but kinda pretty.

parallax7d, I third the sentiment. Why not make the Annai video an FPP?

Okay, but what about women whose carpet doesn't match the drapes? Is there a test for that?
