Why is colour blindness more commonly found in men?

Answer 1

The most common type is red-green color blindness. This type is encoded on the X sex chromosome. Because men have only one and women two, it is much more likely for a men to be colorblind (because women would need two defective X chromosomes).

Other types of color blindness are not dependent on your sex. But they are so uncommon, that it doesn't really change the relation between men and women.

All in all: about 8% of men and only 0.4% of women are colorblind.

Answer 2

A man can be color blind if they get the gene from one parent. If a female gets the gene from one parent they are only a carrier. A female who is color blind has gotten the gene from both parents and that doesn`t happen as frequently.

Answer 3

colorblindness is a genetic defect, and it is tied to the Y chromosome, so men who are XY get it, women who are XX do not. The only women that get colorblindness are those with the rare occurence of XXY chromosome combinations.

Answer 4

I would like to know the same thing. Oh and men lose conscience a lot frequently then women when they get tattoos done. I know that one for the fact. Wonder why?

Answer 5

xy if the x has it the man is colourblind cause the y doesn't count. a woman on the other hand has two xx so if one is colourblind there is still another x that will bo dominant. colorblindness is a receesive gene.

Answer 6

a lot of the maladies are carried on the x chromosome...men only have one, (the other one is the y) so it shows up faster because girls have two X chromosmes and both of her parents have to be affected to have a dominant feature...
