BIOL 112 Lecture Notes - Lecture 3: Genotype Frequency, Allele Frequency, Wilhelm Weinberg
Document Summary
Natural selection increases the frequency of alleles that contribute to reproductive success in a particular environment. Genetic drift causes allele frequencies to change randomly. Gene flow occurs when individuals leave one population, join another, and breed. Mutation modifies allele frequencies by continually introducing new alleles. Natural selection is not the only process responsible for evolution. Each of the four evolutionary processes has different consequences for genetic variation and fitness. The modern synthesis refers to the era in the early 1900s where evolutionary biologists, Hardy weinberg principle , 1908, g. h. hardy and wilhelm weinberg mathematicians, and geneticists collaborated to quantify evolution. Mathematical null hypothesis for study of evolutionary processes. What happens in an entire population when all individuals and thus all possible genotypes bred. Gene pool concept : all of the alleles from all gametes in each generation go into.
