Deleterious mutation accumulation in asexual Timema stick insects.

Molecular biology and evolution - 1 Jan 2012

Henry Lee, Schwander Tanja, Crespi Bernard J

Abstract excerpt

Sexual reproduction is extremely widespread in spite of its presumed costs relative to asexual reproduction, indicating that it must provide significant advantages. One postulated benefit of sex and recombination is that they facilitate the purging of mildly deleterious mutations, which would accumulate in asexual lineages and contribute to their short evolutionary life span. To test this prediction, we estimated...
