- 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.1. An albino man whose parents are both normal marries a woman ome of whose parents is normal and the other albino. She has an albino sister. The couple has a normal son. a.Is albinism a dominant or a recessive trait? Explain your answer B. Give genotypes of all the persons involved. C.The couple plans to have more kids. What is the probability of their second child being normal1)If both parents are heterozygous, which genotypes are possible for their offspring? choose all that apply A)homozygous dominant B)heterozygous C)homozygous recessive D)more information would be needed

What is the probability of their second child being normal?2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd2) A researcher crossed a heterozygous yellow seed plant (Yy) and a recessive green seedplant (yy). Draw a Punnett Square and determine the genotype and phenotype ratios ofthe offspring.
