Sperm competition and the maintenance of polymorphism.

Heredity - 1 Feb 2002

Clark A G

Abstract excerpt

Sperm competition may occur whenever sperm from more than one male are present in the reproductive tract of the female. Studies of field-caught Drosophila reveal that a substantial fraction (80%) of females clearly have sperm from more than one male, and the figure is probably higher because only a small number of progeny are typically surveyed, so a strong skew in paternity can make multiply-mated females appear...
