Chapter 19: Genetic Diversity in Populations

This chapter consists of two sections:

Chapter 19.1: The Hardy-Weinberg Principle
Chapter 19.2: The Causes of Gene Pool Changes

19.2 Causes of Gene Pool Change

Thursday December 5. 2013

In this lesson you will...

outline the conditions that are required in order to maintain genetic equilibrium in a population
identify and compare the effects of mutations, gene flow,non-random mating, and genetic drift on gene pool diversity
distinguish between the founder effect and the bottleneck effect to the microevolution of a population

Tuesday/Wednesday December 3-4 2013

In this Lesson you will....

define a gene pool as the sum of all the alleles for all the genes in a population
describe the gene pool of a population at genetic equilibrium, as well as the molecular basis for a gene pool change
summarize the five conditions upon which the Hardy-Weinberg principle is based
describe how the Hardy-Weinberg equation is used to determine whether a population is undergoing microevolution
calculate allele and genotype frequencies in a population, as well as the number of individuals with specific genotypes and interpret the data
