The evolution of recombination in self-fertilizing organisms [PDF]

open access: yesGenetics, 2022
Abstract Cytological data from flowering plants suggest that the evolution of recombination rates is affected by the mating system of organisms, as higher chiasma frequencies are often observed in self-fertilizing species compared with their outcrossing relatives.

Protandry and Self-Fertilization in the Calyptraeidae [PDF]

open access: yesNature, 1960
ORTON1 suggested that protandrous animals might be self-fertilizing and that this would be advantageous for the spread of a species. He concluded that Crepidula fornicata was self-fertilizing because he found an isolated female guarding veliger larvae. I have kept single Crepidula in aquaria and they have laid fertilized spawn two to three months later.

Independent S-locus mutations caused self-fertility in Arabidopsis thaliana. [PDF]

open access: yesPLoS Genetics, 2009
A common yet poorly understood evolutionary transition among flowering plants is a switch from outbreeding to an inbreeding mode of mating. The model plant Arabidopsis thaliana evolved to an inbreeding state through the loss of self-incompatibility, a ...

Self-fertility in Pseudomonas aeruginosa [PDF]

open access: yesJournal of General Microbiology, 1956
SUMMARY: Two interfertile strains of Pseudomonas aeruginosa were re-examined for evidence of self-fertility. One strain was self-fertile, the frequency of recombination being affected by the manner in which the parent organisms were grown before being combined. The other strain gave no evidence of self-fertility.
