This is the only phenomenon active in a model that uses the expression negative natural log of one minus theta to estimate Reynolds’s distance. Michael Lynch’s barrier hypothesis is partially named after this phenomenon, which is modeled backwards in time to determine coalescence events. (10[1])The null hypothesis for the McDonald–Kreitman test (10[1])states that this phenomenon predominates, (10[1])in accordance with Kimura’s (-5[1])neutral theory. (10[4]-5[2])This phenomenon explains (10[1]-5[1])why (-5[1])the (10[1])time to fixation for an allele is proportional to effective population (10[1])size in the Wright–Fisher (10[2])model for it. (10[1])Pioneer (10[1]-5[1])species are (10[1])subject (10[1])intensely (10[3])to (-5[1])the (10[1])founder effect, (10[3]-5[3])a form (10[2])of (10[1])this phenomenon (10[5]-5[1])that also (10[1]-5[1])manifests (10[2])during (10[2]-5[2])population (10[1]-5[1])bottlenecks. (10[6]-5[5])For 10 points, (10[1]-5[2])name this (10[1])phenomenon where allele distributions (10[1])change randomly. (10[1])■END■ (10[22]0[18])
