More is not better: brood size and population growth in a self-fertilizing nematode.

Abstract excerpt

The normal form of the nematode Caenorhabditis elegans is a self-fertilizing hermaphrodite, which produces from the same germ-line tissue first a limited number of sperm and then a larger number of oocytes. Self-progeny brood sizes are determined by the number of sperm, and most of the oocytes remain unfertilized. Therefore it might seem selectively advantageous to increase the number of sperm, and hence the size...
