What are the offsprings when woman who is a carrier for colorblindness marries a man who has colorblindness?

The most common type of color blindness is a sex-linked trait, meaning the gene is carried on the chromosomes that determine sex. In this case, it's carried on the X chromosome.
There are other types of color blindness that are inherited that are not sex-linked, so it doesn't matter which parent is the carrier.
Males are XY, and therefore can pass either an X or Y to their offspring, making them the actual determinants of the sex of the offspring. Females are XX, and so can only contribute an X. In the case of color blindness, since males only get one X, if that has the gene for color blindness on it, the male will be color blind (in this case, we'll call that one "x" rather than "X". In the case of females, she has two - so if only ONE of her X has the gene, she will be a carrier, but will not have it (Xx). If her father is colorblind (xY), and her mother is a carrier (Xx), she has a 50% chance of being colorblind (she'll either be "xx" or "Xx). If her mother IS colorblind (xx) and her father is too (xY), then there is only one outcome: "xx".
So, if a color blind mother (xx) has children with a non color blind father (XY), there are the possibilities: xX, xY. Her daughters will be carriers, and her sons will be color blind.
If a color blind mother (xx) has children with a color blind father (xY), then these are the possibilities: xx, xY. All children will be color blind.
To sum up, a mother with sex-linked colorblindness will always have color blind sons, and daughters will have a 50% chance of being color blind, depending on if the father is or not.

∙ 15y agoSince the woman is a carrier, one of her x chromosomes has the gene and one doesn't. Since the male has the trait, his only x chromosome has the gene for colorblindness, and he has a normal y chromosome. Also, we know that colorblindness is a sex-lind recessive trait since the woman doesn't show the trait, but carries the gene for it.
The genotype for the woman would be XCXc, while the genotype for the man would be XcY. So when crossed, 50% of female offspring will be carriers, and 50% will have the trait and 50% of male offspring will also be carriers and the other 50% will have the trait for colorblindness.

and neither his parents or brother and sister are color blind

Why can't boys be carriers of colorblindness?
With sex linked traits (the allele is found on the X chromosome) males are either affected or not (they have the defective allele or they don't). Women have two copies of the allele and can be a carrier.
Colorblindness is more common in males than in females because the allele for colorblindness is?
the allele for colorblindness is ressecive NOT dominant. more common in males because they have one x chromosome and women have two, if a deformity is found on the x chromosome in a woman, it can be masked by the other, but still have some sort of side effects, in a male, since he has one, he is effected the most. he has no other genes to mask it.
Why are men more likely than women to be colorblind?
Yes. Because the colorblind trait is a sexlinked trait and is found in the X chromosome that is inherited from the mother, men that only have one X chromosome will develop colorblindness if the trait is found in this gene. For a woman to get it, she would need to have the colorblind gene on both x chromosomes. Therefore the girl´s dad would have to be colorblind and the mother at least a carrier.
What is the man's genotype?
The man's genotype is CcFf. The woman's genotype is CcFf. These genotypes only apply if curly hair is dominant to straight hair. Freckles is dominant to no freckles. Also if a man who is heterozygous for both curly hair and freckles who then marries a woman with the same genotype.
What is population genetics?
if a man has blonde hair and both of his parents have black hair,he marries a woman with blonde hair,her father has blonde hair and her mother has black,they have a child that has blonde hair
The best method for determining if a woman may be a carrier of the trait for color blindness is to?
If she hasn't had a son with red-green colorblindness, then a pedigree could be useful.
What is the probability that a woman who is a carrier of the colorblind gene and a colorblind man will have a daughter who will be colorblind?
the colorblindness is usually not activited in a female body but is usually seen in male
If a color blind male who has normal clotting blood marries a female who is a carrier of hemophilia and has normal color vision could they have a color blind child?
In short, hemophilia has nothing to do with colorblindness, but YES, they could have a colorblind child if she is a carrier for the colorblindness gene. Color blindness is an 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. A woman will carry the colorblindness gene if: a. Her father is colorblind b. Any of her offpsring are colorblind She may carry the colorblindness gene if: a. Male family members (brothers, uncles, etc.) are 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). So, If a woman has normal vision (assuming she does not have a family history of colorblindness), XX, and a man is colorblind, xY, they have several different chances for different offspring: Xx (a normal girl who carries the colorblindness gene) XY (a normal boy) Xx (a normal girl who carries the colorblindness gene) XY (a normal boy) The short answer is that ALL CHILDREN WILL HAVE NORMAL VISION. However, all daughters will be CARRIERS, meaning they can pass colorblindness on to their children.
Does colorblindness occur more frequently in men or woman?
Males.

How do you get barth syndrome?
Barth's Syndrome is not something you get from a virus or a bacteria. It is genetic, on the X chromozome. It means that a women is mostly only a carrier, and when a carrier woman marries a amn, 50% of their boys will have Barth's Syndrome and 50% of their girls will be carriers. All the other boys and girls will be healthy. Have good health, harhanegev@gmail.com
