Module 43 Terms - Hardy-Weinberg Equilibrium

Question 1

Genetic drift

Answer 1

The random change in allele frequencies from generation to generation (like if a large part of a population was suddenly eliminated). Often results from bottlenecks and founder effects

Question 2

Bottleneck

Answer 2

When a large population is reduced to a few individuals

Question 3

Founder effect

Answer 3

When a few individuals from a larger population establish a new population

Question 4

Migration

Answer 4

The movement of individuals from one population to another

Question 5

Gene flow

Answer 5

The movement of alleles from one population to another

Question 6

Nonrandom mating

Answer 6

Individuals preferentially choose mates according to their genotypes

Question 7

What are the five mechanisms of evolution?

Answer 7

Natural selection, genetic drift, migration, mutation, and nonrandom mating

Question 8

Hardy-Weinberg equilibrium

Answer 8

When allele and genotype frequencies don’t change over time. There MUST be random mating, no mutation, no migration, no natural selection, and a large sample size
