Can women be colorblind?

A friend of mines boyfriend is color blind and so is his brother. I had an Aunt that was colorblind, but she also had diabetes and had many surgeries on her eyes. My friend said that a teacher once told her that women cannot be colorblind, only men can. So is this true? Any women out there that are colorblind, or know women that are? Im curious to know. My Aunt just might have been cause she had the diabetes and stuff and I realize I know no other women that are. Thanks in advance.

Its not that they cant bum its just that it its VERY very VERY rare. The reason why is that, as simply as possible, is that men have 2 X chromosome (xx) and women have one x and one y (xy). TO inherit colorblindness, you need to have two infected X chromosomes. So, some women may have one infected, and can pass it on to their son, but they wont express the trait (they are homozygous). There is a lot more science and biology and genetic disorder things behind it all, but that basically it. Although it would seem impossible for a women to get it, it has and can indeed happened (its just not very likely)

I'm female and I'm colorblind. I've never heard only males were colorblind. Thats news to me. I'm diabetic too so that may have something to do with as well.... I'm seriously wondering about this now. I may have to do some research on this subject.....
