The _____________ refers to a reduction in observed heterozygosity within a population due to population structure. It occurs when what is assumed to be a single, randomly mating population is actually composed of two or more subpopulations with limited gene flow between them. Each subpopulation may be in Hardy-Weinberg equilibrium, but when combined into a single “population,” the overall heterozygosity is lower than expected. Choose the right term to fill in the blank.
