The Evolution of Polyandry: Sperm Competition, Sperm Selection, and Offspring Viability (2005, background): “…“genetic diversity” hypothesis proposes that, by increasing genetic diversity within progeny, females guard against future environmental uncertainty (Yasui 1998, 2001); and the “sexy-sperm” hypothesis proposes that, by inciting sperm competition, females produce sons that are successful in…”
Bet-hedging and the evolution of multiple mating (2003, background): “Despite good theoretical reasons to expect genetic bet-hedging to be a significant factor influencing the evolution of multiple mating (but see Yasui, 2001), there is little empirical evidence of its importance (Yasui, 1997, 1998).”
Multiple paternity and sperm storage lead to increased genetic diversity in Anolis lizards (2007, background): “Rather, we suggest that females engage in a sort of genetic bet-hedging (Yasui, 2001), in which mating with multiple males allows the female to diversify her progeny genotypes and increase their likelihood of survival in unpredictable environments.”
