View Full Version : Calling all color-blind men

Greetings BTT members,

I was sitting here lost in thought about my red-green color-blindness and my thinking led me to something I think might be worth pursuing.

I hear all this business about the X-linked AR gene. Well, why don't we figure out just how much influence it has? We know red-green color-blindness is an X-linked recessive trait. I have it, and I know my maternal grandfather wasn't colorblind, therefore I must have received it through my maternal grandmother's family.

Here's what I propose: any men who know for sure they are red-green colorblind investigate your family history of color-blindness. If you find any other color-blind men in your family tree, compare your hair loss to theirs. It's probable that you share the same exact x-chromosome, AR-receptor and all. While the X-linked color-blindness gene could come from various X-chromosomes within our family trees, this should at least narrow the scope a bit.

I think if we pool our results, we can get some kind of idea of what effect this gene actually has.

What do you all think?

On second though, this probably won't do much, I didn't realize mothers pass on genes from both of their X-chromosomes to their sons. How disappointing...
