Step-by-step explanation:
Colorblindness is carried on the X chromosome and is a recessive trait. Three children are left orphans when their parents are killed in an automobile crash. The physician finds that the boy is colorblind, one girl is colorblind, and the second girl has normal color vision. What are the
genotypes and phenotypes of each parent (Do not use a Punnett square), Hemophilia is a X-linked recessive trait. Suppose you are a marriage counselor and a young woman comes to you for advice. She tells you that her brother has hemophilia, but both her parents are normal. She wishes to marry a normal man and wants to know the probability of the disease in children she may have. What would be the possible genotypes and phenotypes of both
female and male children (Do not use a Punnett square)?
