Can a normal non carrier female have a colorblind child?
Besides, can a colorblind female have a son with normal vision?
As long as there's one working gene, they will have normal color vision. See, if a woman is colorblind, that means she has the nonworking gene on both X chromosomes. Since sons almost always get their only X chromosome from their mom, chances are they will be colorblind too.
Consequently, what is the genotype of a female who is not color blind but is a carrier of red green color blindness?
Explanation: XX because she is female. Since she is not color blind one of the pair has to be XC. Since she is a carrier of color blindness she has to have the recessive gene as well, so the other has to be Xc.
The daughters who are carriers can have color blind sons with the same logic. If they have children with a man who is not color blind, then each daughter has a 50% chance of being a carrier and each son has a 50% chance of being color blind.
