text: Severe environmental change can drive a population extinct unless the population
adapts in time to the new conditions (“evolutionary rescue”). How does biparental
sexual reproduction influence the chances of population persistence compared to
clonal reproduction or selfing? In this article, we set up a one‐locus two‐allele
model for adaptation in diploid species, where rescue is contingent on the establishment
of the mutant homozygote. Reproduction can occur by random mating, selfing, or
clonally. Random mating generates and destroys the rescue mutant; selfing is efficient
at generating it but at the same time depletes the heterozygote, which can lead
to a low mutant frequency in the standing genetic variation. Due to these (and
other) antagonistic effects, we find a nontrivial dependence of population survival
on the rate of sex/selfing, which is strongly influenced by the dominance coefficient
of the mutation before and after the environmental change. Importantly, since
mating with the wild‐type breaks the mutant homozygote up, a slow decay of the
wild‐type population size can impede rescue in randomly mating populations.
