Document Summary
Group of actual or potentially interbreeding individuals of the same species. All the genetic material within a population. If h- w assumptions are satisfied, allele frequencies will not change from one generation to the next. H- w serves as a model for defining the expected genetic distribution if no evolutionary change occurs. # individuals with genotype divided by # individuals in population. Animals are members of the same species if normal males and females are actively or potentially capable of mating and producing fertile offspring in a natural environment. Population that is clearly isolated geographically and/or socially from other breeding groups. Hardy- weinberg describes and predicts genotype and allele frequencies in a non- evolving population. The population is said to be in h- w equilibrium. Effects genotypic frequencies but not allele frequencies. Mating with individuals from groups other than their own increases chance of new variation. Mating with individuals from the same group decreases chance of new variation.
