The Bigger Picture: From Populations to Evolution
Key Concepts
Population genetics is the study of allele frequecies in groups of organisms of the same species in the same geographic area
Final Destination
Population genetics looks at phenotype and genotypes among large numbers of individuals. Allele frequencies reveal the underlying rules. Tracking allele frequencies from one generatin to the next an reveal evolution in action -- or if allele frequencies don't change, the state of Hardy-Weinberg equilibriu.
Population Genetics Underlies Evolution
A popultion is any group of members of the same species in a given geographical area who are potentially capable of mading and producing offspring.
All of the alleles in a population constitue the gene pool.
Comparing Genomes among species reveals evolutionary relatedness.
Population genetics is a branch of genetics that considers all the alleles in a population, which constitute a gene pool.
On a broader level, shifting allele frequencies in population reflect small steps of genetic change, called microevolution.
The gene in a population comprise its gene pool
Microevolution reflects changes in allele frequencie in populations. It is not occuring if allele frequencies stay constant over generations (Hardy-Weinbery equilibrium).
Five factors can change genotype frequencies: nonrandom mating, migration, genetic drift, mutation and natural selection
