Blood type is an example of a common multiple allele trait. There are 3 different alleles for blood type (A, B and O). A is dominant to O. B is also dominant to O. A
and B are both co-dominant. If the father has the genotype Bi and the mother has
the genotype 1A1B, what are the expected phenotypes of their children?
A. 1A: 2 AB: 10
B. 1A: 2 AB: 1 B
C. 1 AB: 2 B:1 A
D. 1 AB:2 0:1 B
