BILD 3 Study Guide - Midterm Guide: Genotype Frequency, Panmixia, Bild
Document Summary
You should be able to: population genetics and evolutionary processes: define and use correctly the following terms: hardy-weinberg equilibrium, locus, allele frequency, genotype frequency, genetic drift, gene flow, non-random mating, hardy-weinberg equilibrium. A mathematical model that predicts no change in genotype or allele frequencies in a population under certain conditions. A description of what the gene pool looks like in the absence of evolution. Specific location or position of a gene, dna sequence on a chromosome: allele frequency. Relative frequency of an allele: genotype frequency. Relative frequency of a genotype: genetic drift. Change in the genetic composition of a population caused by chance events. Fixation: all members of the population have the same alleles of a particular gene: gene flow. Can bring in genotypes from a neighboring population. Transfer of alleles into/out of a population as a result of the movement of fertile individuals or their gametes. Can counteract the loss of genetic variation caused by drift: non-random mating.
