Laboratory 8: Population Genetics And Evolution
Block 6
BACKGROUND INFORMATION
The Hardy-Weinberg theory suggests that evolution occurs through changes in frequencies in alleles. The reason for this lab is to find what effect altering the environment has on the equilibrium. In the lab, P is the representation of the dominant trait, and q is the representation of the recessive one. The formula of the Hardy-Weinberg equilibrium is p2+2pq+q2=1. There are also five conditions which need to be met in order to satisfy this equilibrium:
The mating is random
There is no natural selection
No presence of gene flow
No mutation of alleles allowed
The breeding population is sufficiently large
PURPOSE OF EXPERIMENTS
The objective of the lab is to gain a better understanding of how the Hardy-Weinberg equilibrium works and how natural selection affects allele frequencies in populations. We also study the relationship between evolution and changes in allele frequency.
