Maintenance of high inbreeding depression in selfing populations: Two-stage effect of early- and late-acting mutations.

Abstract excerpt

High estimates of inbreeding depression have been obtained in many plant populations with high selfing rates. However, deleterious mutations might be purged from such populations as a result of selfing. I developed a simulation model assuming the presence of mutations at two sets of loci, namely, early- and late-acting loci, and the selective abortion of embryos coupled with ovule overproduction. In the model,...
