Question

a normal woman whose father was colorblind is married to a normal man the sun would be

Answer 1

If a normal woman, whose father is color-blind, marries a normal man, what will the children be?

I’m assuming that by “normal” you mean “not color-blind”, and that you’re asking about whether the children will be color-blind or not.

Color-blindness is carried on the X chromosome. Men, being XY, will either be color-blind or not. Men cannot be carriers. Women, being XX, can be color-blind (if both X chromosomes carry the color-blindness gene), carriers (if only one of their X chromosomes carries the gene), or completely free of the gene.

So, we know that the woman is not color-blind, but that her father was. This means she is a carrier of the gene. She marries a man that is not color blind, and thus doesn’t carry the gene at all. If they have children:

If they have a son, that son will have a 50% chance to be color blind.If they have a daughter, that daughter will have a 50% chance to be a carrier.

A woman cannot be color blind unless her father is color blind and her mother is either color-blind or a carrier. Since the father in this case is not color-blind, any daughters they have cannot be color-blind; at worst, they’ll be carriers.

As an example, my maternal grandfather was color-blind. My mother is a carrier, my father has normal color vision. I inherited color-blindness from my mother; that was a 50% chance, and it came up color-blind. My sister has a 50% to be free of the gene, and a 50% chance to be a carrier. We won’t know which way it went until/unless she has a son that is color blind. (Her husband isn’t color-blind, so if they have a son that isn’t color-blind, that could be mere chance, and any daughters they have will not be color-blind so we won’t be able to tell whether they’re carriers or free of the gene.)

Answer 2

Probability of children is colorblind or not

Explanation:

• Color blindness is carried on the X chromosome. Men, being XY, will either be partially blind or not. Men can't be transporters. Ladies, being XX, can be colour blind (if both X chromosomes convey the visual weakness quality), bearers (if just one of their X chromosomes conveys the quality), or totally liberated from the quality.  
• Thus, we realize that the woman isn't colour blind, however, that her father was. This implies she is a transporter of the quality. She weds a man that isn't visually challenged, and in this way doesn't convey the quality by any stretch of the gene and if they have children:  
• If they have a male child, that child will have a 50% probability to be color-blind
