Document Summary

Chapter 6: mendelian genetics in populations i- selection and. How much genetic diversity exists in a typical population: early efforts to study allelic diversity in populations were based on allozyme electrophoresis. Isolating proteins from a large sample of individuals, separating the proteins in an electrophoresis gel, and then staining the gel to visualize the proteins produced by a particular gene. Genetic variation is extensive: genetic diversity is maintained by natural variation. 6. 1| mendelian genetics in populations: the hardy-weinberg equilibrium. A numerical calculation: punnett squares can be used to predict genotypes of offspring by making crosses between two heterozygotes, can also calculate genotype frequencies among the zygotes by multiplying allele frequencies. The hardy weinberg equilibrium principle yields two fundamental conclusions: the allele frequencies in a population will not change, generation after generation. If the allele frequencies in a population are given by p and q, then genotype frequencies will be given by p2, 2pq, q2.
