The maintenance of sperm variability: context-dependent selection on sperm morphology in a broadcast spawning invertebrate.

Evolution; international journal of organic evolution - 1 May 2013

Johnson Darren W, Monro Keyne, Marshall Dustin J

Abstract excerpt

Why are sperm so variable despite having a singular, critical function and an intimate relationship with fitness? A key to understanding the evolution of sperm morphology is identifying which traits enable sperm to be successful fertilizers. Several sperm traits (e.g., tail length, overall size) are implicated in sperm performance, but the benefits of these traits are likely to be highly context dependent. Here,...
