The eyes have it: Men do see things differently to women
The way that the visual centers of men and women’s brains works is different, finds new research published in BioMed Central’s open access journal Biology of Sex Differences. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.
Well I’m red-green colorblind so I never stood a chance anyway. If it isn’t in a box of 8 crayons/markers, I don’t attempt to use that color’s name generally, cuz I will never pick the right shade. All the fuschias, magentas, maroons, burnt siennas, teals, cyans, etc. of the world can fuck off.
Isn’t colorblindness almost exclusively found in males too?
Probably oversimplifying, but it’s something about the mutation being on the X chromosome, meaning women have a backup X and men don’t.
It is possible for someone with two X chromosomes to still be colorblind, but since this gene is recessice you have to have the mutation on both chromosomes, which makes it way more rare.
It’s not really a backup X. In any given cell in a woman’s body, one of the X chromosomes has been inactivated into something called a Barr body. The remaining X chromosome is then the active one.
Women carriers of the gene defect for protan (causing protanopia in males) exhibit Schmidt’s Sign, an abnormal insensitivity to long wavelengths (red light). This is due to the highly skewed L:M cone ratio caused by the defective gene.
You pretty much nailed it
I know a colorblind XX person. But he’s a trans man, so make of that what you will.
