[3 marks. Recommended time = 5 min.] Some people are hypersensitive to the smell of asparagus, and can even detect a strong odor in the urine of a person who has recently eaten asparagus. This trait turns out to have a simple genetic basis. An individual with one or two copies of the A allele at the gene (AA or Aa genotypes) can smell asparagus in urine, whereas a person with two copies of the alternative \"a" allele (aa genotypes) cannot. Assume that men and women in the population have the same allele frequencies at the asparagus-smelling gene and that marriage and child production are independent of the genotype at the gene. In the human population, 8% of alleles are A and 92% are a. What are the odds that an Aa father and aa mother have one child that is hypersensitive to the smell of asparagus and one child that is not
