TY - BOOK AU - Fearnhead,P. TI - Perfect Simulation From Nonneutral Population Genetic Models: Variable Population Size and Population Subdivision N2 - We show how the idea of monotone coupling from the past can produce simple algorithms for simulating samples at a nonneutral locus under a range of demographic models. We specifically consider a biallelic locus and either a general variable population size mode or a general migration model for population subdivision. We investigate the effect of demography on the efficacy of selection and the effect of selection on genetic divergence between populations UR - https://drive.google.com/file/d/1HmO40H4qqZhJXacNqu1F9uXnT0e-rXkn/view?usp=drivesdk ER -
