The Ishihara Test is a color perception test used to detect deficiencies for which colors?

Seems like lots of people fail this test at traffic lights!

I've heard color blindness is more prevalent in males

great info!!!

The gene for red/green colour blindness is on the part of the x-cromosome that has no equivalent on the y-cromosome. The gene is recessive, but since men only have one x-cromosome they are more likely to show the colour blindness.

Wonder why occurs in first place

MAE, Yes, and other "sex linked" conditions are almost always only suffered by males. Haemophilia is one of them.

nimblemoon, good one!!!😊

Player #3833664, We pass our genes on to our children and there is some degree of mutation.

Is that where colour blindness was first detected?
