Abstract excerpt

Sexual reproduction is ancient and ubiquitous despite its obvious disadvantages1. Theory predicts that the reassortment of alleles that results from sex is necessary for natural selection to act effectively on individual loci; therefore, a purely clonal organism should rapidly accumulate deleterious mutations and go extinct2-4. Nevertheless, many asexual species have existed for longer than theory predicts is...
