Concept

Problem: Blood type in humans is controlled by multiple alleles of the same gene. The A and B alleles of this gene are codominant, while the O allele is recessive. A man with AB blood marries a woman with BO (IBi) blood genotype. What are the expected genotypes and phenotypes of their offspring? A. How many phenotypes result from a cross between the two parents in the interactive?B. What percentage of the offspring are predicted to have the B blood phenotype? C. For an individual with O type blood, what would the blood cell look like in the interactive?a) a different shape of antigensb) no antigensc) triangle-shaped antigens d) both triangle and circle-shaped antigense) circle-shaped antigens
