There is growing interest in the possibility that genetic compatibility may drive mate choice,
including gamete choice, particularly from the perspective of understanding why females …

… effort per spawning) in relation to the number, N i , of males competing at spawning of type
i in the intensity model, assuming that a male can assess N i at the time of ejaculation. Thus, …

A popular notion in sexual selection is that females are polyandrous and their offspring are
commonly sired by more than a single male. We now have large-scale evidence from natural …

Why do females typically mate with more than one male? Female mating patterns have broad
implications for sexual selection 1 , 2 , speciation 3 and conflicts of interest between the …

… females, there is still no correlation (r = 0.29, n = 40, P = 0.26). Additionally, in another
experiment (Wedell and Tregenza, unpublished manuscript) where males were mated to two …

Meiotic drivers are genetic variants that selfishly manipulate the production of gametes to
increase their own rate of transmission, often to the detriment of the rest of the genome and the …

Sperm competition is thought to be responsible for the tremendous inter- and intraspecific
variation in sperm number 1 and size 2 . But why several animals produce a range of sperm …

Male-killing bacteria are widespread in arthropods, and can profoundly alter the reproductive
biology of their host species. Here we detail the first case of complete suppression of a …
