In humans, nearsightedness (myopia) and the enzyme disorder PKU (phenylketonuria) are both inherited as independently assorting autosomal recessive traits. Use N to represent the dominant allele for normal vision and n for the recessive allele for nearsightedness. Use P to represent the dominant allele for the normal enzyme and p for the recessive allele for phenylketonuria. A woman is nearsighted and heterozygous from the normal enzyme. Her husband has the normal phenotype for both traits, although his father is nearsighted and his mother has phenylketonuria. a. What is the genotype of the husband? (2 points) b. What is the probability that a child of this couple is nearsighted and phenylketonuric? (2 points) c. What is the probability that a child of this couple is normal for both traits? (2 points) c. What is the probability that a child of this couple is a girl who is nearsighted and phenylketonuric? (2 points)
