Sexual partners for the stressed: facultative outcrossing in the self-fertilizing nematode Caenorhabditis elegans.

Evolution; international journal of organic evolution - 1 Jun 2009

Morran Levi T, Cappy Brian J, Anderson Jennifer L, Phillips Patrick C

Abstract excerpt

Sexual reproduction shuffles genetic variation, potentially enhancing the evolutionary response to environmental change. Many asexual organisms respond to stress by generating facultative sexual reproduction, presumably as a means of escaping the trap of low genetic diversity. Self-fertilizing organisms are subject to similar genetic limitations: the consistent loss of genetic diversity within lineages restricts...
