It is known that the defective gene is carried on the X chromosome, so males are almost exclusively the victim, and white males make up practically the entire percentage of victims. 8 percent of all males are color blind.

The gene for color blindness is a recessive allele located on the x chromosome. If a color blind man and color blind woman have one son and three daughters how many will be color blind?
Women can not be colorblind, only men. For questions like these a punnett square is useful. Men can not carry the colorblind trait, but women can. I know this is kind of confusing. When a carrier ( a woman with the color blind trait) has children with a man ( color blind or not) her kids will have 50% chance of having that trait. If its a girl, she will be the carrier. If its a boy, he will have the colorblind trait. SO TO ANSWER YOUR QUESTION: Theoreticaly, 1 of the daughters will be the carrier, and the son will have a 50% chance of being colorblind. Women can be colorblind, its just rare. About every 6400 women one is colour blind and with men, every 80 men 1 is colour blind.
Can only men be colour blind?
More men are color blind than women because the recessive gene for color blindness is carried by women on one of their X chromosomes. And since they have two X chromosomes, the recessive trait is less likely to be expressed. Since men have an X and a Y chromosome, which is shorter, if a mother passes on her X chromosome with the trait of color blindness, her son will have no corresponding gene on his Y chromosome from keeping it from being expressed. So men are color blind more often than women.
How do you know you are the color blind ones and the people who are color blind aren't?
I don't think that there is an answer to that question
A color-blind woman mates with a male with normal color vision Which of these results would indicate that color blindness is caused by an X-linked recessive allele?
All the sons would be color-blind and none of the daughters are color-blind.
Who carries the color blindness gene?
Color blindness is a defect in the x chromosone. Women always provide an X chromosone in their eggs. Men can either deliver an X or a Y chromosone in their sperm. Both men (XY) and women (XX) carry it. But it is more prevalent in men because they only have one X chromosone, whereas women have two X chromozones and it is very unlikely that both would be defective.
What percent of people are colorblind?
About 8 percent of males, but only 0.5 percent of females, are color blind in some way or another, whether it is one color, a color combination, or another mutation. This is due to males only having one X chromosone - But that's another story.
What percent of men experience some form of color blind?
"Depending on just which figures you believe, color blindness seems to occur in about 8% - 12% of males of European origin..." (Color/ Zelanski & Fisher/ 6th ed.)
