Father: Type AB blood
The father's genotype: IAIB
Mother: Type B blood
The mother's genotype: IBi
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 antigens
b) no antigens
c) triangle-shaped antigens
d) both triangle and circle-shaped antigens
e) circle-shaped antigens
