1. In hamsters, B is a dominant allele coding for black fur and w is a recessive allele coding for white fur. Match up the appropriate probabilities of mating outcomes with the parental genotypes.
Probabilities Matching Outcomes All offspring are black A. ww x ww All Offspring are white B. Bw x ww There is a 50% chance offspring are either black or white
C. BB x ww The chance of a white offspring is 25% D. Bw x Bw
2. The following question deals with the ABO blood group. Recall that A and B alleles are co-dominant over the allele O. Jill, who has type AB blood, marries Jack who has type B blood, but whose mother has type O blood. What are the genotypes of Jack, Jill, and Jack's mother?
A. Jack: B
Jill: AB
Jack's Mother: O
B. Jack: BB
Jill: AB
Jack's Mother: OB
C. Jack: BBO
Jill: ABO
Jack's Mother: OOO
D. Jack: BO
Jill: AB
Jack's Mother: OO
E. Jack: BB
Jill: AB
Jack's Mother: OO
