Maternal effects contribute to the superior performance of extra-pair offspring.

Current biology : CB - 12 May 2009

Abstract excerpt

The explanation for extra-pair mating in female birds remains poorly understood and contentious [1-7]. Several leading hypotheses propose that females benefit indirectly by enhancing the genetic quality of their offspring, through good genes or genetic compatibility effects [1, 8, 9]. Supporting this idea, recent studies have identified a range of fitness-related traits for which extra-pair offspring (EPO) are...
