Three alleles, A, B, and O, govern human blood typing. Alleles A and B are codominant with each other, and both are dominant to type O. A second gene affecting blood type is Rh-factor, which gives the blood a plus (+) or a minus (-). The Rh+ allele is dominant to the Rh- allele. What would be an expected phenotype of a cross between a woman who has AB blood and is Rh+ to a man who has O blood and is Rh-?
A. The offspring could be B-
B. The offspring could be A+
C. The offspring could be O-
D. The offspring could be AB+

Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?
