Population Genetics

Population Genetics. Evolution depends upon mutation to create new alleles. Evolution occurs as a result of population level changes in allele frequencies. What evolutionary forces alter allele frequencies?. How do allele frequencies change in a population from generation

Population genetics

Population genetics. Evolution in more detail. Populations. Group of individuals of the same species in a given area All of the genes in a population = their gene pool All alleles at all loci. Outline. 1. Modern Evolutionary Synthesis 2. Individuals live or die, but POPULATIONS evolve

Genetic Diversity in Populations Terminology

Genetic Diversity in Populations Terminology. A gene pool is the sum of all the alleles for all the genes in a population. Population geneticists study gene pools. Genotype frequency : the proportion of a population with a particular genotype. Normally expressed as a decimal.
