Study Notes
Population Genetics, Natural Selection, and Genotype-Phenotype Interactions
- Migration affects allele frequencies and can lead to genetic divergence or similarity between populations
- The fixation index (Fst) is used to estimate genetic divergence between populations, with higher Fst values indicating less migration
- Non-random mating, such as assortative mating and inbreeding, can lead to changes in allele frequencies and an increase in homozygotes
- Inbreeding depression can result from an excess of homozygous genotypes with recessive detrimental alleles, leading to harmful effects in populations
- Natural selection, proposed by Charles Darwin, is the driving force behind adaptive evolution and can lead to genetic improvement in populations
- Different types of natural selection include stabilizing, directional, and balancing selection, which can affect the distribution of traits within a population
- Fitness is the relative ability of genotypes to survive and reproduce, and the selection coefficient measures the selective disadvantage of a disfavored genotype
- Predicting changes in allele frequencies involves considering relative fitness, probability of reproduction, and the impact of natural selection on genotype frequencies
- Mutation, genetic drift, and selection all interact to influence the evolution of new phenotypes and the distribution of alleles within populations
- Population genetics tools, such as allele and genotype frequencies, can be used to estimate inbreeding rates, population size, migration, and recent changes in population sizes
