Sperm Models
‘‘Good-sperm’’ models predict positive genetic associations between a male’s sperm competitiveness and the general viability of his offspring, whereas ‘‘sexy-sperm’’ models predict that multiple mating females produce sons successful in sperm competition, and daughters that incite sperm competition through multiple mating. As with precopulatory processes, postcopulatory models predict that the trait in males that determines fertilization success will become genetically coupled with the mechanism by which females bias sperm use toward preferred males.

Famous quotes containing the word models:
“French rhetorical models are too narrow for the English tradition. Most pernicious of French imports is the notion that there is no person behind a text. Is there anything more affected, aggressive, and relentlessly concrete than a Parisan intellectual behind his/her turgid text? The Parisian is a provincial when he pretends to speak for the universe.”
—Camille Paglia (b. 1947)
