Occasional sex in an 'asexual' polyploid hermaphrodite.

Proceedings. Biological sciences - 22 May 2004

Abstract excerpt

Asexual populations are usually considered evolutionary dead-ends because they lack the mechanisms to generate and maintain sufficient genetic diversity. Yet, some asexual forms are remarkably widespread and genetically diverse. This raises the question whether asexual systems are always truly clonal or whether they have cryptic forms of sexuality that enhance their viability. In the planarian flatworm Schmidtea...
