Whether the absence of a block to self-fertilization indicates that eggs are routinely self-fertilized in the field is not known, although the converse (self-sterility) clearly implies that self-fertilization does not occur in nature.

Seed harvested from the two parents of each cross was kept separate to examine whether any self-fertilization had occurred (Table 2).
Isozyme analysis supports allotetraploid inheritance in tetraploid creeping bentgrass (Agrostis palustris Huds.)
Nevertheless, self-fertilization has intrinsic genetic or energetic advantages that can lead to its rapid expansion in a population (see Fisher 1930), and as a consequence, many species, particularly plants, have evolved mechanisms that facilitate reproduction by partial self-fertilization (Schemske and Lande 1985; Barrett and Eckert 1990).
Mutation and extinction: the role of variable mutational effects synergistic epistasis, beneficial mutations, and degree of outcrossing
Scientists studying the genes that help some kinds of mustard plants avoid self-fertilization have new evidence that at least one of those genes helps form the shape of the much-studied Arabidopsis, also of the mustard family.
Genes prevent inbreeding, aid development
Six animals were spawned by immersion in 1 mM serotonin, or by temperature shock (12), and self-fertilization was allowed to occur.
Development of genetically tagged bay scallops for evaluation of seeding programs
Inbreeding depression is thought to be the major genetic factor opposing the evolution of self-fertilization, countering the automatic transmission advantage of selfing first demonstrated by Fisher (1941).
Inbreeding depression under joint selfing, outcrossing, and asexuality
Botanists have struggled to piece together how some plants avoid self-fertilization -- and the loss of genetic diversity that goes hand-in-hand with it -- ever since Charles Darwin noticed that some plants can fertilize themselves while others cannot.

In hermaphrodites, the potential for self-fertilization is a concern, and genetic analyses of paternity may be required to conclusively exclude selfing in some taxa (Yund and McCartney, 1994).

Inbreeding depression has been studied extensively as an important factor in the evolution of self-fertilization in plants, and is thought to be present in most sexual species (Charlesworth and Charlesworth 1987).
