Cystic fibrosis (f) and deafness (d) are caused by two unlinked autosomal recessive alleles, and colorblindness is caused by an X-linked recessive allele Xc. A female who is deaf and is a carrier for cystic fibrosis and colorblindness marries a male who is colorblind and is a carrier for cystic fibrosis and deafness. I. What are the female's and male's genotypes? II) What is the probability their first child is a phenotypically normal female? Enter your answer as percent without the percent sign to two digits (e.g. 12.34). III) What is the probability their first child is a phenotypically normal male?
The next four questions go together. Cystic fibrosis (f) and deafness (d) are caused by two unlinked autosomal recessive alleles, and colorblindness is caused by an X-linked recessive allele Xc. A female who is deaf and is a carrier for cystic fibrosis and colorblindness marries a male who is colorblind and is a carrier for cystic fibrosis and deafness.

III) What is the probability their first child is a phenotypically normal male? Enter your answer as percent without the percent sign to two digits (e.g. 12.34).
IV) What is the probability their first child has all three conditions ? Enter your answer as percent without the percent sign to two digits (e.g. 12.34).
