Summary[edit]

Description Figure 4. Sperm competition. (A) Hermaphrodite-derived spermatozoa wait in the spermatheca, where they fertilize nearly all oocytes that pass through the spermatheca. (B) A hermaphrodite after being inseminated by relatively few male-derived (blue) sperm will produce a mixture of self (pink embryo) and outcross (blue embryo) progeny. (C) A hermaphrodite after being inseminated by many male-derived (blue) sperm will produce only outcross (blue embryo) progeny. As noted by others, male-derived sperm are ~50% larger than hermaphrodite-derived sperm (LaMunyon and Ward, 1995; LaMunyon and Ward, 1998). Adapted from Singson et al. (1999).
