1. In humans, red-green color blindness is recessive and X linked, whereas albinism is recessive and autosomal. What will be the genotypes and phenotypes of the children resulting from a marriage between a woman with albinism and normal vision, and a man with normal skin pigmentation and color blindness, each of whom is homozygous for the traits displayed?
2. In chickens, a dominant sex-linked gene (B) produces barred feathers, and the recessive allele (b), when homozygous, produces nonbarred (solid-color) feathers. Suppose a nonbarred cock is crossed with a barred hen.
a. What will be the phenotype of the birds?
b. If an female is mated with her father, what will be the phenotype of their offspring?
c. If an male is mated with his mother, what will be the phenotype of their offspring?
