Document Summary
Perform a restriction enzyme digest of your amplified dna. Population genetics: evolution the change in allele frequencies through time. For groups called populations: population a group of individuals of the same species. All living in the same area so they have the potential to interbreed: allele frequencies the proportions of different alleles of a gene in a population. Hardy-weinberg law: if all other factors remain constant, the frequency of particular alleles will be constant from generation to generation. This is genetic equilibrium: evolution the change in allele frequencies through time. Occurs when genetic equilibrium is upset: gene frequencies of a particular generation depend upon the gene frequencies of the previous generation and not upon the genotype frequencies. Factors that upset genetic equilibrium: nonrandom mating, migration gene flow, selection, mutation, a small population size. Assumptions of hardy-weinberg equilibrium: random mating, no migration. No gene flow: no selection, no mutation, a very large population.
