2. In humans, blood type is a result of multiple alleles: IA, IB, and i0. A few simple rules of blood type genetics are that: - IA is dominant over i0, 0 IB is dominant over i0, and - IAIB are codominant. Two parents who are heterozygous for type A blood and carry sickle cell trait have children. a. What is the genotype of the parents? b. What are the genetic makeups of all the possible gametes they can produce? 0. Make a list of the possible phenotypes that their offspring could be, and their respective probabilities
