title: Evolution: vertebrate reproductive strategies get mixed up.
abstract: The mangrove killifish is the only vertebrate known to have a mixed-mating strategy, where hermaphrodites reproduce by either self-fertilisation or cross-breeding. New molecular evidence from this species reveals that occasional cross-breeding between common hermaphroditic individuals and rare pure males results in an injection of genetic variation into otherwise highly homozygous 'clonal' lineages.
