Genetic variation in released gametes produces genetic diversity in the offspring of the broadcast spawning coral Acropora tenuis.

Abstract excerpt

All coral species in the genus Acropora are broadcast-spawning hermaphrodites. Fertilization in the ocean requires sufficient numbers of gametes from conspecifics and the contact time for fertilization is thought to be limited by the rapid diffusion of sperm. Many studies have reported a positive correlation between sperm concentration and fertilization success, but it is not clear how gametes diffuse in seawater...
