This model must be observed to conduct QST-FST analysis. This model is disrupted by “hitchhiking” that occurs due to linkage disequilibrium. Complementary factors in this model accounting for fixation and panmixia were proposed by Sewall Wright. The Wahlund effect refers to a change in the F-statistic, which indicates a deviation from this model. The instability of this model’s (15[1])(*) inbreeding coefficient causes it to be less useful for measuring a reduction in heterozygosity (10[1]-5[1])of an observed population. Infinite population size is assumed in this model, a central equation of which sets [read slowly] “p squared plus 2 times p times q plus q squared” equal to one. For 10 points, name this (-5[1])doubly-eponymous model in which a population’s allele frequencies remain constant in a (-5[1])namesake (10[3]0[3])“equilibrium.” ■END■
