Valerie Henderson 11/12/07 Lab #11 Population Genetics Abstract : Charles Darwin is credited for proposing a mechanism for evolutionary change. This mechanism is natural selection and accounts for the differential survival and reproduction of individuals in a population. In 1908, English mathematician G.H. Hardy and German physician W. Weinberg independently developed models of population genetics that showed the process of heredity by itself didn’t affect the genetic structure of a population. The Hardy-Weinbergy theorem states the frequency of alleles in the population will remain the same regardless of the starting frequencies. The equilibrium genotypic frequencies will be established after one generation of random mating. There are certain conditions which must be met for this theorem to be true: the population must be large, matings are random, there are no net changes in the gene pool due to mutation, there is no migration of individuals into and out of the population, and there is no selection. This provides a baseline model in which gene frequencies don’t change and evolution doesn’t occur. Introduction
