Examples of self-fertilization


self-fertilization
The evolution of self-fertilization and inbreeding depression in plants.
No progeny were identified as the products of self-fertilization in this population.
Broadly speaking, greater self-fertilization decreases element number under deleterious insertion and increases element number with regulation through ectopic exchange.
However, self-fertilization should be interpreted cautiously with respect to only 8 loci in a relatively small number of individuals analysed.
Such expectations are badly needed to built realistic models of the evolution of self-fertilization.
In order for reproduction by self-fertilization to evolve, the advantages must outweigh any possible disadvantage of inbreeding.
The genetic variability is therefore expected to be halved in populations with very high frequencies of self-fertilization.
Also, self-fertilization, as mentioned above, is expected to promote local population differentiation.
Suppose the offspring is to be produced through self-fertilization.
Some reproductive factors affecting the selection of self-fertilization in plants.
Animals mix it up too: the distribution of self-fertilization among hermaphroditic animals.
Eggs are produced by self-fertilization (most trematodes are hermaphroditic), bypassing the need for the worm to mature in a definitive host.
Outbreeding, self-fertilization, gynogenesis and triploidy would influence the recombination of alleles between individuals and hence the degree of genetic diversity generated by each fluke.
Under these circumstances, homozygosity associated with self-fertilization is ineffective at reducing average element number.
Expectations for inbreeding depression on self-fertilization of tetraploids.
