Hardy Weinberg Equilibrium

Question 1

What is a population? What defines a population?

Answer 1

A group of organisms that live together in a defined area
Can interbreed w/ different populations
When a population becomes fragmented, separate populations form

Question 2

What is a Gene Pool? Is variety a good or bad thing?

Answer 2

The sum of all the alleles for all the genes in a population
More variety is better

Question 3

What is Evolution?

Answer 3

Change across successive generations in the heritable characteristics of biological populations

Question 4

What is the Hardy Weinburg Pinciple?

Answer 4

If allele frequencies stay the same over time w/ each generation the population is stable & unchanging
No evolution is occurring

Question 5

What are the Five conditions for HWE?

Answer 5

Large Population (no genetic drift)
Random Mating (no choosing mates)
No mutations - no changes to alleles
No Immigration/Emigration
No Natural Selection

Question 6

What are the two equations for HWE?

Answer 6

Genotype, p2 + 2pq + q2 = 1

Allele, p + q = 1

p2 = Frequency of Homozygous Dominant individuals
p = Frequency of Dominant Alleles
2pq = Frequency of Heterozygous individuals
q2 = Frequency of Homozygous Recesssive individuals
q = Frequency of Recessive Alleles
