Inbreeding and outbreeding depression in Caenorhabditis nematodes.

Evolution; international journal of organic evolution - 1 Jun 2007

Dolgin Elie S, Charlesworth Brian, Baird Scott E, Cutter Asher D

Abstract excerpt

The nematode Caenorhabditis elegans reproduces primarily by self-fertilization of hermaphrodites, yet males are present at low frequencies in natural populations (androdioecy). The ancestral state of C. elegans was probably gonochorism (separate males and females), as in its relative C. remanei. Males may be maintained in C. elegans because outcrossed individuals escape inbreeding depression. The level of...
