ABO blood types are inherited via a single autosomal gene with 3 alleles. Allele A (IA) and allele B (IB) are co-dominant to recessive allele O (i). Sarah has type B blood. Scott has type AB blood.
a. Is it possible that a biological child of Sarah and Scott inherit the phenotype of type O blood? Briefly explain your answer.
b. Suppose that Sarah and Scottâs first child has type A blood. What are Scott and Sarahâs genotype? What proportion of Scott and Sarahâs future offspring are expected to have blood type AB?
Scott:
Sarah:
Proportion of future offspring expected to have blood type AB:
