Genetics! You are a genetic counselor. You are counseling a woman and a man, as described below. As a genetic counselor, you know (1) dry (as opposed to wet) earwax is an autosomal recessive trait and (2) red-green colorblindness is an X-linked recessive trait. Represent the alleles as follows:
1. W = wet earwax; w = dry earwax
2. XR = red-green color vision; Xr = red-green color blindness; Y = Y chromosome (which has neither allele)
3. The woman has dry earwax. She has red-green colorblindness. What is the woman's genotype?
4. The man is heterozygous for wet earwax. He does not have red-green colorblindness. What is the man's genotype?
5. What are the possible gamete genotypes that the woman can produce? Remember: Gametes are haploid and have one allele for each gene.
6. What are the possible gamete genotypes that the man can produce?
7. The woman and the man are planning to have children. What is the probability that a daughter will have neither dry earwax nor red-green colorblindness? What is the probability that a son will have neither dry earwax nor red-green colorblindness?
