3. A student states, “If a person expresses the dominant trait for eye color, then the person’s genotype must be BB.” Is the student correct? Explain why or why not. Assume that the B allele is dominant, and the b allele is recessive.)
3. A couple just had a baby, who has type-O blood. Upon learning the baby’s blood type, the father becomesinfuriated and accuses the mother of cheating on him. The mother has type-A blood and the father has type-Bblood. Knowing that the allele for type-O is recessive, answer the following questions.a. What is the relationship between the IA, IB, and i alleles?b. Is the father right? Or is he falsely accusing the mother? Explain. Include the genotypes of the parentsand the genotypes of their potential children.
