ANTH 1001 Lecture Notes - Lecture 7: Allele Frequency, Genotype Frequency, Null Hypothesis
Document Summary
How do we measure evolution: at the population level of an organism an individual cannot successfully reproduce by themselves and therefore cannot evolve, but a group of individuals can successfully reproduce a view of evolution. Population: a group of organisms potentially capable of successful reproduction: individuals of a population tend to choose mates from within the group, the largest reproductive pupation is the species. If the population is the unit of evolution then the gene pool is the sum of all alleles carried by the members of a population. Evolution is a change in allele frequencies from one generation to the next. When there is no change occurring, you say it is at a genetic equilibrium which is no changes in allele frequencies, no evolution is occurring in the population. Used to determine whether or not evolutionary forces are operating on the population, for a given genetic locus. No di erence in allele or genotype frequencies > no evolution.
