Sexual selection for good genes is based on the assumption that ‘good genes’ are equally good
for all females. In contrast, selection for genetic compatibility is based on the assumption that
offspring viability will depend on the interaction between male and female genotypes, and
hence one male may not be good for all females. Here we present a simple model to examine the
relationship between the genetic compatibility hypothesis and good genes sexual selection. We
examine the circumstances under which selection arising from genetic compatibility will favour
an increase in the number of males a female mates with. Our model shows that if there is some
cost of mating, then some form of sperm selection based on compatibility is essential for the
evolution of polyandry for compatibility. Furthermore, we found that when both good genes
and compatibility selection are in operation, selection for compatibility can reduce directional
sexual selection by causing females to mate with males of lower genetic quality.

Maintenance costs of male dominance and sexually antagonistic selection in the wild
Boratynski, Zbigniew; Koskela, Esa; Mappes, Tapio; Mills, Suzanne; Mökkönen, Mikael (Wiley-Blackwell Publishing Ltd., 2018)Variation in dominance status determines male mating and reproductive success, but natural selection for male dominance can be detrimental or antagonistic for female performance, and ultimately their fitness. Attaining and ... -
Sex-specific assumptions and their importance in models of sexual selection
de Vries, Charlotte; Lehtonen, Jussi (Elsevier BV, 2023)Sexual selection is a field coloured by tension and contrasting views. One contested claim is the causal link from the definition of the sexes (anisogamy) to divergent selection on the sexes. Does theory truly engage with ... -
Do the benefits of polyandry scale with outbreeding?
Burdfield-Steel, Emily; Auty, Sam; Shuker, David M. (Oxford University Press; International Society for Behavioral Ecology, 2015)There have been many potential explanations put forward as to why polyandry often persists despite the multiple costs it can inflict on females. One such explanation is avoidance of costs associated with mating with ... -
Female Sexual Signaling in a Capital Breeder, the European Glow-Worm Lampyris noctiluca
Baudry, Gautier; Hopkins, Juhani; Watts, Phillip C.; Kaitala, Arja (Springer, 2021)Theory predicts that because costs constrain female sexual signaling, females are expected to have a low signaling effort that is increased with passing time until mating is secured. This pattern of signaling is expected ... -
Size-selective harvesting fosters adaptations in mating behavior and reproductive allocation, affecting sexual selection in fish
Sbragaglia, Valerio; Gliese, Catalina; Bierbach, David; Honsey, Andrew E.; Uusi-Heikkilä, Silva; Arlinghaus, Robert (Wiley-Blackwell Publishing Ltd., 2019)The role of sexual selection in the context of harvest‐induced evolution is poorly understood. However, elevated and trait‐selective harvesting of wild populations may change sexually selected traits, which in turn can ...
