Chapter 16 Evolution of Populations Vocab

Gene pool

• refers to the total collection of genes in a population

• refers to the proportion of a particular allele within a population, compared to the total number of alleles of that gene

• traits that are determined by the interaction of multiple genes rather than a single gene

• a type of natural selection where one extreme phenotype is favored over the other, leading to a shift in the distribution of traits in a population towards that extreme phenotype

NGSS.HS-LS4-3

refers to the random fluctuations of gene frequencies in a small population, which can result in changes to the genetic makeup of a population over time

• Genetic equilibrium

• Genetic drift

• Hardy- Weinberg Principle

• Hardy-Weinberg equilibrium

refers to the complete set of genes or genetic material that an organism inherits from its parents and determines its physical traits, characteristics, and potential for development

• Stabilizing selection

• Genetic makeup

• Genetic equilibrium

• equilibrium
