Random mating

c

Small population size

d

No gene flow

2. Genetic drift is most significant in populations that are:

a

Large and stable

b

Small and isolated

c

Under strong natural selection

d

Experiencing high gene flow

1. The total aggregate of genes in a population at any one time is called the  .

2.   is the transfer of alleles or genes from one population to another.

3. The primary source of new alleles in a population is  .

1. Explain the concept of allele frequency and how it is calculated.

2. Describe the bottleneck effect and its impact on genetic diversity within a population.

1. Natural selection always leads to an increase in genetic variation.

T

True

F

False

2. The Hardy-Weinberg principle can be used to estimate genotype frequencies in a population.

T

True

F

False

Examine the image of the DNA double helix below. Briefly explain how mutations in this structure can lead to changes in allele frequencies within a population.
