Document Summary

Biology 121 lecture 19 population genetics. Objectives: calculate frequency of alleles contributed by generation in population, assumptions of hardy-weinberg theory, what contributes to changing allele frequencies. Bent grass grows on heavy metals usually toxic: populations on mines are genetically different from those that are not. Population genetics: focuses on contribution of alleles to population, quantification of genetic variation in population, measure changes in population over time, evolution change in allele frequencies. 6/20 = 0. 3 a2: note: p + q = 1 (allele frequencies) Hardy-weinberg equilibrium: p^2 + 2pq + q^2 = 1 (genotype frequencies, frequency of getting combination alleles.
