Self-fertilizing roundworms have smaller genomes

Some species of hermaphroditic nematode roundworms, including Caenorhabditis briggsae, are capable of ‘selfing’ — reproducing without a mate.

A recent collaborative study led by researchers at the University of Maryland demonstrated that hermaphroditic C. briggsae roundworms have smaller genomes than worms that do not self-fertilize.
