Men are more likely to be color blind than women. This is primarily due to the fact that color blindness is often linked to the X chromosome, and since men have one X and one Y chromosome, a single recessive gene for color blindness on their X chromosome can result in the condition. Women, having two X chromosomes, are less likely to express color blindness unless both of their X chromosomes carry the gene for it. Consequently, approximately 8% of men and only about 0.5% of women are affected by color blindness.

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.
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.
Who is most likely to be affected by color blindness?
Color blindness is more common in men than in women, with an estimated 1 in 12 men being affected compared to 1 in 200 women. This condition is usually inherited and is more prevalent among Caucasian populations.
How do you get the disease of color blindness?
You do not get color blindness, you are either born with it or not born with it. It is on the X chromosome. A male has one X chromosome. A woman has 2 X chromosomes. If one X chromosome does not have red-green capability and the man has that chromosome, then he is color blind. A woman can have one color blind chromosome and one non-color blind chromosome and she will not be color blind. The ability to see blue and yellow is on chromosome number 7. Everyone has two of those. A man can only have 3 color chromosomes. Women can have 4 color chromosomes. Since the chromosomes can be slightly different, women can frequently see far more color variations than men can see.
Why hemophilia and color blindness occur much more often in men than in women?
It is due to two factors. One is that these traits are coded on the x-chromosome, of which women have two, men only one (since it is paired with a y-chromosome in men). The other factor is that the two traits are both recessive, that is they are suppressed in the presence of the dominant, healthy allele. In men there is no other x-chromosome, which could provide a healthy allele to counteract the effect of the mutant alleles, therefore these disorders occur more frequently. However, due to mosaicism, and x-chromosome inactivation (Barr-body formation), women who carry the color-blind x-chromosome have color-blind patches in their retinas, or may even be nearly completely color-blind in one eye.
What is the ratio of girls who are colour blind?
I don't know the ratio but I know that men are more likely to become colour blind because women have a backup gene.
Why did tiresias become blind?
He was blinded by Hera for his judgment than women enjoyed sex more than men.
What percent of men are color blind?
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.
Are blind men sexier to women?
maybe, maybe not but mostly NO
Are women prone to color blindness than man?
Studies show that color blindness affects 8% of Caucasian men and only 0.5% of Caucasian women. Therefore, while the color deficiency is mostly a male dominated affliction, some women are also affected. It is believed that color-blindness comes from a gene on the X chromosome and thus would be part of life from birth. However, it has been discovered that color-blindness can occur with some diseases such as liver disease.
Why do men choose ugly women over beautiful women?
