You are a genetic counselor. As a genetic counselor, youknow:
-Dry (as opposed to wet) earwax is an autosomal recessivetrait.
-Red-green colorblindness is an X-linked recessive trait.
-Sickle-cell anemia is an autosomal recessive trait.
-The genes for these traits (see above) are located on differentchromosomes.
You are counseling a woman and a man, as described below.
Question A. The woman is heterozygous for wet earwax. She hasred-green colorblindness. What is the woman’s genotype?
Question B. What are the possible gamete genotypes that she canproduce?
Question C. The man has dry earwax. He not have red-greencolorblindness. What is the man’s genotype?
Question D. What are the possible gamete genotypes that he canproduce?
Question E. The woman and the man are planning to have children.What is the probability that a daughter will have neither dryearwax nor red-green colorblindness? What is the probability that ason will have neither dry earwax nor red-green colorblindness?Hint: Complete a Punnett square
