A.    genotype frequencies
B.    allele frequencies
C.    gene frequencies
D.    phenotype frequencies
E.    Any of these frequencies may be used.

2.    Which of the following is(are) an allele(s) found almost exclusively among Native Americans and populations in the area(s) from which Native Americans likely derived?

A.    S
B.    A1, A2
C.    Dia
D.    N
E.    Ka, Kb

3.    What is the minimum allele frequency (of the least common allele) required for a trait to be considered polymorphic?

A.    0.001
B.    0.005
C.    0.01
D.    0.05
E.    0.1

4.    The O allele is the most common among all humans for the ABO gene locus. What is the allele frequency range for O?

A.    0.20 to 0.38
B.    0.60 to 0.90
C.    0.55 to 0.80
D.    0.40 to 1.00
E.    0.63 to 0.75

5.    All of the following are polygenic traits in humans except

A.    body form.
B.    nose shape.
C.    skin pigmentation.
D.    facial shape.
E.    tongue rolling.

6.    Regarding adaptation,

A.    physiological, genetic, and developmental adaptations are irreversible.
B.    physiological, genetic, and developmental adaptations are biologically based.
C.    behavioral and sociological adaptations are culturally based.
D.    physiological, developmental, and behavioral adaptations operate on the group level.
E.    All of these are correct.

7.    True or False: Genetic distances are represented using matrices, dendrograms, scatter plots, and regression formulas.

8.   
True or False: A haplogroup haplotype, which is used in population studies, is a set of alleles from linked gene loci that are inherited as a unit from one parent.

9.    
True or False: Many disease-causing pathogens resemble A-B-O antigens and, in persons with the appropriate blood types, are not recognized as foreign substances to which the immune system should respond.

10.  
True or False: Physiological adaptations to heat stress are vasodilation and sweating, while physiological adaptations to cold stress are vasoconstriction, shivering, insulation, and increased basal metabolic rate.
