Document Summary
Individuals of a population tend to choose mates from within the group. A group of organisms potentially capable of successful reproduction. The largest reproductive population is the species. Important concept because the population is the entity that evolves, it is the unit of evolution that changes from one generation to the next. Gene pool is the sum of all alleles carried by the members of a population. Allele frequencies is a distinct concept from genotype frequency, genotype frequencies refer to individual outcome (two alleles coming together) Evolution is a change in allele frequencies in a population from one generation to the next. Genetic equilibrium = no changes in allele frequencies, i. e. no evolution is occurring in the population. Used to determine whether or not evolution forces are operating on the population, for a given genetic locus. Measure observed genotype frequencies for specific traits, and compare them against predicted genotype frequencies assuming no evolution is occurring.
