In this lesson, students explore a model of genetic drift in populations of varying sizes. The lesson uses the model to help students to understand the ramifications of population size and isolation on alleles in populations.
Learning Objectives:
-
Describe how genetic drift influences the diversity (polymorphism) of alleles in a population
-
Investigate the consequences of very small or very large populations for allele diversity.
-
Compare the effects of genetic drift in isolated populations
-
Apply these ideas to real-world populations of animals (including dog breeds and certain human ethnic groups)
