Blood Type Inheritance Blood type genetically determined according to the following rules: Genotype (allele combination) Phenotype (blood type) AO or AA Type A BO or BB Type B AB Type AB OO Type O A child’s genotype is a combination of the genotypes of his or her parents. Each parent contributes an allele to the genotype, as evident in these examples: Parents genotype Child genotype AO and AA AA or AO AA and BB AO and BB AO and BO AB AB, BO AB, AO, BO, OO In the following problems, determine the probability of an offspring’s genotype using a punnett square. 1) Mother’s genotype – OO; Father’s genotype – BO. What is the probability that the child will have a. Type O blood __________ b. Type B blood __________ c. Type AB blood _________ 2) Mother’s genotype – AB ; Father’s genotype – AA. What is the probability that the child will have a. Type AB blood _______ b. Type B blood ________ c. Type A blood ________ 3) Mother’s blood type – A; Father’s blood type O. What are the possible genotypes that the mother and father could have? a. Mother ___________________ b. Father ____________________ Is it possible for the child to have Type O blood? _______________ What would be the genotype of the child in that case? ____________ Is it possible for the child to have Type A blood? ________________ What would be the genotype of the child in that case? ____________
