Genetics Of Mendelian Populations

. Comparison of expectations from blending versus particulate heredity materials. Nature and importance of population genetics; the Hardy-Weinberg equilibrium principle for crossbreeding populations. Factors causing the upset of this equilibrium and the shift of gene frequencies--mutation, selection, random genetic drift, migration. These factors are the principal cause of evolution. (lecture), Explains the nature and importance of population genetics. Derives the Hardy-Weinberg equilibrium principle for Mendelian (cross-breeding) populations. Points out that though the Hardy-Weinberg law produces a static gene pool when it applies, mutation, selection, random genetic drift, and migration upset this equilibrium and cause gene frequencies to shift-these factors being, therefore, the principal causes of evolution.
