ANTH 1001 Lecture Notes - Lecture 8: Allele Frequency, Genotype Frequency, Gene Pool
Document Summary
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 population is the species. Gene pool = sum of all alleles carried by the members of a population. Evolution = a change in allele frequencies from one generation to the next. Genetic equilibrium = no changes in allele frequencies i. e. no evolution is occuring. Used to determine whether or not evolutionary forces are operating on the. Measure observed genotype frequencies for specific traits, and compare them population, for a given genetic locus against predicted genotype frequencies assuming no evolution is occuring. Is about the gene pool in a population. There are 4 allele combinations for every trait. A population is in equilibrium when the allele combinations stay the same. When the combinations change, the population is evolving. Factors occurring in natural populations that cause changes in gene frequencies.
