Although some plants can get away with self-fertilization, in other plants it leads to "inbreeding depression," harmful effects that come from being too inbred.

Some self-fertilization, however, should weaken the harmful effects of inbreeding by exposing genetic load to selection. This study examines the maintenance ...

In this article, we study the effect of self-fertilization on the evolution of a modifier allele that alters the recombination rate between two selected loci.

The scientists examined existing variation in the gene used by many members of the Solanaceae family, which include tomatoes and tobacco, to recognize and reject their own pollen, thereby avoiding self-fertilization and the harmful effects of inbreeding.

I present a phenotypic model of the selection of self-fertilization that applies to any mode of selfpollination. A novel factor, seed discounting-the loss of outcrossing maternal fitness accompanying an increase in self-fertilization-is introduced, and pollen discounting is reformulated. ... harmful-male...

As a result, some plants have evolved a self-incompatibility mechanism that prevents self-fertilization and the harmful effects of inbreeding. In many species of plants, the self-incompatibility function is encoded by a single gene.

The tendency of organisms to reproduce by cross-fertilization despite numerous disadvantages relative to self-fertilization is one of the oldest puzzles in evolutionary biology.
