EXPLAIN: The gene for red-green colorblindness is located on the X chromosome. Does the mother or father pass the gene for colorblindness to sons?  Explain your answer.

Red-green colorblindness is caused by a mutation in a gene on the X-chromosome. Colorblindness is inherited in an X-linked recessive manner. Bob (dad) is colorblind. Karen (mom) can see color.

Bob and Karen have a child named Taylor, who can see color.

Taylor has children with someone who is colorblind. They have 12 children. All the female children can see color and all the male children cannot

Taylor is most likely:

A.Male

B.Female

C.Taylor is equally likely to be male or female

Colorblindness and hemophilia A both recessive traits. The two genes are located 10cM apart on the X chromosome. A phenotypically normal man with no family history of either disease is married to a phenotypically normal woman, whose father has hemophilia A and mother is colorblind. If this couple has a son..

Part A

what is the probability that he will have neither hemophilia nor colorblindness?
