The concept of __________ is most likely to maintain genetic variation in populations by favoring rare alleles.

When deleterious recessive alleles are present in a population at a low frequency, the rate at which selection will remove them from the population is __________ (low/high).

A hypothetical population has two alleles for a gene: L and R. In a random sample of individuals, 97 are homozygous for L, 127 are homozygous for R, and 112 are heterozygous. What is the frequency of L?

When highly deleterious mutations are being rapidly introduced into a population, the equilibrium frequency will be __________ (low/high).

The concept of __________ is most likely to remove deleterious alleles in populations.

Consider a locus with two alleles, A and a. Under which of the following scenarios will the frequency of the A allele increase?

Refer to the figure below.  In this figure, the allele frequency (p) of an island is on the y-axis, and generational time is on the x-axis.  Each line represents a different migration rate from the mainland.  What can you conclude about how migration rates alter allele frequencies?  Can you determine anything about the mainland population allele frequencies from the graph?

Which of the following genotypic fitness values would result in the most rapid fixation of the beneficial allele, A?

Among the many variations of proteins on the surface of the human red blood cell are those resulting from variation at the MN locus. Two alleles (M and N) and three genotypes (MM, MN, and NN) are distinguished by blood typing. From a sample population of people from Yavin 4 (for all those Star Wars fans out there…), we get the following number of people carrying each genotype: MM = 211, MN = 127, and NN = 17. Is the population in Hardy-Weinberg equilibrium?

A client has been taking isoniazid for a month and a half. The client complains to a nurse about numbness, paresthesia, and tingling in the extremities. The nurse interprets that the client is experiencing which side effect?
