Knowing that colorblindness is a recessive sex-linked trait (specifically X-linked), show a cross between a female who is a carrier for the disease with a male who is NOT colorblind. What is the probability that a female offspring would be colorblind? 0%

0%

Explanation:

For a female offspring to be colorblind she would need to inherit an X chromosome with the disease from both parents. It is impossible for her father to be a carrier for the disease without having it because he only has one X chromosome so if he carried it he would have symptoms. Therefore, he does not have a chromosome that carries colorblindness so it is not possible for them to have a colorblind daughter.

the correct answer is sex-linked recessive.
