Biology Chapter 16.1

Population Genetics The study of the frequency and interaction of alleles and genes in populations.
Microevolution A change in the collective genetic material of a population.
Bell Curve On a graph of the frequency of some variable, a curve that first rises and then falls and thus forms a symmetric bell-shaped curve.
Gene Pool All of the genes of the reproductively active members of a population.
Allele Frequency The proportion of gene copies in a population that are a given allele, expressed as a percentage.
Phenotype Frequency The ration of individuals with a particular phenotype to the total number of individuals in a population.
Hardy-Weinberg Genetic Equilibrium Genotype frequencies in a population tend to remain the same from generation to generation unless acted on by outside influences.
