Chapter 14, Problem 14TYK

In humans, earwax can be wet or dry. The form of earwax is determined by a single gene, and the “wet” allele (W) is dominant to the “dry” allele (w). A woman and her mother both have wet earwax, but her father has dry earwax. Her partner is a man whose parents both had dry earwax. What are the genotypes of the woman and the man, respectively?

  1. a. Ww, ww
  2. b. ww, Ww
  3. c. Ww, Ww
  4. d. ww, ww

In humans, hair color and structure are determined by two independent pairs of genes. The dominant gene  T  determines dark hair color, and the recessive allele  t - light hair; The dominant gene  S  determines the formation of curly hair, and its recessive allele  t - straight hair. What kind of hair will the children have if the mother has light, straight hair, and the father has dark, curly hair (one of the pairs of traits is heterozygous for both parents)?
In guinea pigs, an allele for rough fur (R) is dominant over an allele for smooth fur (r), and an allele for black coat (B) is dominant over an allele for white fur (b). What would be the genotype of a guinea pig with smooth black fur?
Skin color in humans is determined by polygenic inheritance, which means the more dominant alleles there are, the darker the skin color will be.   A medium-toned skinned woman (AaBb) has a child with another medium-toned skinned man (AaBb). What is the probability of them having a very dark-toned skinned child? (Hint: the genotype is homozygous dominant)
