Anther-stigma separation is associated with inbreeding depression in Datura stramonium, a predominantly self-fertilizing annual.

Abstract excerpt

Genetically based variation in outcrossing rate generates lineages within populations that differ in their history of inbreeding. According to some models, mating-system modifiers in such populations will demonstrate both linkage and identity disequilibrium with fitness loci, resulting in lineage-specific inbreeding depression. Other models assert that differences among families in levels of inbreeding depression...
