Does mate limitation in self-incompatible species promote the evolution of selfing? The case of Leavenworthia alabamica.

Evolution; international journal of organic evolution - 1 Jun 2010

Busch Jeremiah W, Joly Simon, Schoen Daniel J

Abstract excerpt

Genetic diversity at the S-locus controlling self-incompatibility (SI) is often high because of negative frequency-dependent selection. In species with highly patchy spatial distributions, genetic drift can overwhelm balancing selection and cause stochastic loss of S-alleles. Natural selection may favor the breakdown of SI in populations with few S-alleles because low S-allele diversity constrains the seed...
