Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following is NOT a condition for Hardy-Weinberg equilibrium?
No mutation
Random mating
Small population size
No gene flow
2. Genetic drift is most significant in populations that are:
Large and stable
Small and isolated
Under strong natural selection
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.
True
False
2. The Hardy-Weinberg principle can be used to estimate genotype frequencies in a population.
True
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.
