While the chromatic genes are on the X chromosome and this does give girls a statistical advantage, really most men and women are more or less the same. Most people are trichromats with 3 types of colour sensors, however there is a certain type of colourblindness only in men where they have a defficient X gene and only end up with 2 types of sensors. With women, they can't get the dichromatic defficiency because of the redundant X gene. Instead, they can sometimes end up with 4 types of sensors and can see even more colours than everyone else - they see shades of colour in between colours that everyone else sees as the same.

So having XX genes doesn't help you see better or distinguish colours, it just changes the likelihood of either a slight defficiency or a slight extra proficiency - but most likely you'll be about the same as everyone else.

Imma need more than a "trust me bro" on this.

Ha! I almost put that info in my post. But, also you got the fact wrong.

No XX people don't see more color vibrantly, but XY are indeed more likely to be color blind. But honestly the rate at which XY chromosome men are more color blind is nowhere near the amount of guys that can't tell the difference between colors. Absolutely more men are red-green colorblind due to heredity, but that doesn't explain why the majority of men claim to not be able to see the difference between all sorts of different color sets that are similar.

I mean come on, stop and think why this even got posted. It's a well known trope that isn't explained by a few % more XY people being colorblind.

No. It’s not guaranteed that females can see more colors. It’s almost impossible for males to do so (XXY chromosome grouping, which is also rare), but it’s also fairly rare for women to be able to see more colors. Females can also be colorblind, but it’s very rare: both X chromosomes you get from your parents must carry the deficient gene.

That's nice.

Well yes, but that is besides the point of what I'm saying? Of course the choice doesn't matter, they are functionally the same, just not exactly the same. No one would come out and say that DEF the right is better and the left sucks.

But they ARE different. I mean this works as a joke here in shit posting because it's a well known thing that a lot of men will say there is NO difference. That's not true.
