a)

A. polygenic

b)

B. codominance

c)

C. multiple alleles

7.

Human blood type is determined by multiple alleles (A, B, and O). Which ratio would result from a cross between a man with Type AB blood and a woman with Type O blood?

a)

A. 50% Type A, 50% Type O

b)

B. 75% Type A, 25% Type B

c)

C. 50% Type A, 50% Type B

d)

8.

Which principle best explains why the gametes only each contain a single allele?

a)

A. Mendel's Law of Dominance states that dominant alleles must separate from recessive alleles in gamete formation.

b)

B. Mendel's Law of Inheritance states that only one allele is inherited from each parent and the dominant allele is inherited first.

c)

C. Mendel's Law of Segregation states that alleles must segregate during gamete formation in order to create haploid sex cells need for reproduction.

d)

D. Mendel's Law of Independent Assortment states that each trait is inherited separately and the resulting gametes each only contain the DNA for a single trait.
