Color blindness is the inability to differentiate between different colors. The most common type is red-green color blindness. This occurs in 8 percent of males and 0.4 percent of females. It occurs when either the red or green cones are not present or not functioning properly. People with this problem are not completely unable to see red or green, but often confuse the two colors. This is an inherited disorder and affects men more commonly since the capacity for color vision is located on the X chromosome. (Women have two X chromosomes, so the probability of inheriting at least one X with normal color vision is high; men have only one X chromosome to work with. The inability to see any color, or seeing only in different shades of gray, is very rare.


Women can be color blind, but only if their father is. If they got a carrier gene from their color blind father and one from their mother, they would be homozygous recessive, and therefore would be colorblind. Actually I am a woman and my dad is color blind and I am not.

The answer says a woman can be color blind only if her father is. In your case, you had a chance of being color blind because your dad is.

Another answer

Not all women who are color blind has their father color blind. I - being female, I am partially color blind and cannot tell what different color shades are sometimes. Meaning I when dark purple is put in front of me I see light purple. Or if red is in front of me, I see pink. Vice versa, and same with other colors. My father is not color blind. I am not sure that this is color blindness that you have. It seems that you have a color vision defect called Protanomaly, where your color deficiency has to deal with saturation. When someone is color blind it has to deal with hue of the color. This form of color deficiency is also rare.


Color blindness is yummy X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind. Since women have two X chromosomes, both must be affected in order for her to be colorblind. A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy). Thus, her father must be colorblind, and her mother must be a carrier (or colorblind), and she must receive a copy of the affected chromosome. For the female offspring to be color blind, the father must be color blind. A father with normal vision would produce heterozygous female offspring and they would be a carrier.


OK girls can not get colorblind only guys have the chromosome gene because the women gives the X and the guy determines if it a boy or girl the colorblind is in the Y chromosome if you get that one your a guy i know this my mom works at a hospital girls can not become colorblind.

_ok im not the one who posted this but i am here to say that's bull crap my mom is fully color blind and can only see black white and shades of gray like those old movies. its do to a mutation of cells in there eyes that kicks out color cones


I just got done studying genetics and yes it is VERY RARE but women can be colorblind. If a female gets a bad X-chromosome from mom then she is a carrier and can pass it to her son but if she gets a bad one from her mom then her dad would have to have a bad one for her to be colorblind, which is what makes it rare that she would get a bad one from her mother and her dad would be colorblind. She could just get the bad one from dad if he is colorblind but a good one from mom and still be just a carrier.


I am a woman who is red--green colorblind. The trait is carried on the X chromosome. Males receive an X chromosome from their mother and a Y from their father. If the X carries the trait of colorblindness, the male will be colorblind. Females need to receive two defective X chromosomes to be colorblind, one from their father and one from their mother. If a women has only one defective X chromosome, she will be a carrier of the trait. My father was red-green colorblind and so was my mother's father, making my mother a carrier of the trait, although she is not colorblind herself. I have two sisters who are not colorblind, as they each received a non-defective X chromosome from my mother. I knew before my son was born that he would be red-green colorblind, as the X chromosome he received from me carried the trait.

If you mean 'males' by male humans, then no. It is more common for men to be color blind, but women (though rare it is) can be 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.

A woman who has a color-blind mother and a father with normal color vision marries a carrier man with normal vision This couple has a son What is the chance that the son is color-blind?

The son will be color-blind. Color-blindness is a recessive trait found on the X-chromosome, and for someone to be color-blind all present X-chromosomes MUST have the recessive trait. Therefore, a son from a color-blind mother (who receives the trait from his mother on the X-chromosome) will always be color-blind, regardless of the state of the father (who can only give his son a Y-chromosome). This is why color-blindness is more commonly found in men than in women, since men only require one X while women must have two X carrying the trait present. All of the daughters of this couple will be carriers of color-blindness, but will not be color-blind.

Why are more men than women color 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 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.

Do the parents have to be color blind in order for the kid to be color blind?

no, they dont even HAVE to be blind. you can be color blind without even close relatives or any with color blind history in their past.

Why are women rarely color blinded?

The colour blind gene is normally carried by females meaning that they are rarely affected by it. Men on the other hand are often effected and are very likely to be partially colour blind if their grandfather on their mothers side was also colour blind. However, some women can be colour blind if one of their parents is colour blind.

If a color blind man has a color blind daughter then the mother has to be color blind as well?

Not nessesarily. The mother can be either color-blind or simply a carrier of the gene.

most likely because the dominant genes from the parents will transfer over to the offspring and will make the offspring color blind too.
