Wikipedia
Selfing or self-fertilization is the union of male and female gametes and/or nuclei from same haploid, diploid, or polyploid organism. It is a extreme degree of inbreeding.
Selfing is widespread – from unicellular organisms – to the most complex hermaphroditic plants and animals (especially invertebrates). In unicellular organisms such as Protozoa, selfing can occur when two individuals (or their cell nuclei) interbreed that were produced from a previous mitotic division of the same individual.
Among hermaphrodite animals there are some that regularly reproduce by self-fertilization. In others, it is a rare event; selfing in such species is more common in adverse environmental conditions, or in the absence of a partner.
Usage examples of "selfing".
The selfing of F1 hybrids will often give rise to the variation needed in the F2 generation for selecting parents for subsequent gen- erations, even if the characteristics of the original parents of the F1 hybrid are not known.
