Yeah, affect as a noun, can be used in psychological contexts, referring to an observable expression of emotion, but this usage doesn't fit the title about color vision.
The gene that codes for red sensitive receptors in the eye is on the X chromosome; of which females have two, while males have only one plus a Y chromosome. You receive an X from your mother and either an X or a Y from your father. If a girl (XX) receives an X with a mutated receptor gene from one parent it's not a problem because she has another copy of that gene on her other X chromosome. However, if a boy (XY) gets an X chromosome with a faulty gene then he has no back up and can't produce functioning red receptors.
@@radupopescu9977 it is because the females have to pick good mates, better senses like seeing millions of extra color gradients allows them to pick better partners. This happens in a lot of species and it gets so ridiculous that males in a lot of species have very elaborate patterns that they themselves cannot see. Read "An Immense World" by Ed Yong.
BBC? Affect?? Affect means mood, a feeling. Which is prob what colour is. If those glasses can change the colour ‘out there’, colour must be mental. Surely.
Affect? You mean «How colour vision affects you?» or «The effects of colour vision»? In any case, the current title is wrong.

Chad. They changed it
irony in the lesson "if you see red, you're *not* dead" in this case
Thank you for sharing it.
Why do the males and females have different color vision?
Perhaps this ability is an early adaptation of this species. Natural selection will spread it over time.
Good question, it's also worth noting that red-green colour blindness is more common amongst human males than females.

Very good question! And none of the responses give until now, are satisfying.
Unfortunately I don't know either.

Yeah... maybe steer closer to the accurate and proofed titles.

Hehe
indeed. There is no red. only the sensation of red generated by your brain.
There must be an advantage to being colour blind. Otherwise, the colour blind would have died out.
Excellent copy editing.

Affect? lol
