    Abstract

    In the nematode Caenorhabditis elegans, a single gene (plg-1) encodes the dominant protein found in mating plugs - a means of inhibiting multiple matings. Naturally occurring loss of plg-1 function results in males that fail to deposit mating plugs - a manifestation of relaxed sexual selection since the evolution of self-fertilization in this species.
