Drift in small populations predicts mate availability and the breakdown of self-incompatibility in a clonal polyploid.

Abstract excerpt

Mate limitation in small populations can reduce reproductive fitness, hinder population growth, and increase extinction risk. Mate limitation is exacerbated in self-incompatible (SI) taxa, where shared S-alleles further restrict mating. Theory suggests genetic drift as a predictor of mate limitation and the breakdown of SI systems. We tested this prediction by evaluating mate availability and S-allele number in...
