Many fitness benefits of polyandry have been proposed. We addressed four hypotheses that are relevant to the agile antechinus, Antechinus agilis, a highly promiscuous marsupial: polyandry (1) involves females 'trading up' to obtain good genes for offspring; (2) promotes sperm competition/sperm choice to obtain good genes; (3) enables females to avoid genetically incompatible gene combinations (specifically inbreeding); or (4) enables females to avoid infertility. We tested the predictions of...[Show more]
