Kin selection on one hand, and gamete interactions in post-ejaculatory sexual selection on the other are two major research themes that have risen to prominence over the past half century and have simultaneously developed into central fields of research in evolutionary biology. There is a natural connection between the two: when gametes interact with each other, very commonly many of them originate from the same parent and are thus siblings. For example, sperm competition will almost always involve competition between sibling gametes even if the interacting parents are not related to each other. If parents are related to each other, the relatedness between gametes increases further. Here we discuss the relation between kin selection on one hand, and gamete competition, gamete limitation, local gamete competition, and the evolution of sex allocation on the other. To illustrate these topics, we present a novel model on sex allocation in simultaneous hermaphrodites under sperm limitation and limited, costly dispersal. We find that sperm limitation can significantly increase allocation into male function, but limited dispersal (and thus increased relatedness) does not alter sex allocation regardless of the presence of sperm limitation.

The relative roles of natural and sexual selection in the evolution of tardigrade gamete morphology
Ryndov, Serge (2021)Siittiösolut ovat eläinkunnassa esiintyvistä solutyypeistä monimuotoisin ryhmä. Siittiösoluissa esiintyvän muuntelun on useissa eläintaksoneissa havaittu olevan yhteydessä parittelun jälkeisen seksuaalivalinnan tasoon sekä ... -
The correlation between anisogamy and sexual selection intensity : the broad theoretical predictions
Lehtonen, Jussi; Parker, Geoff A (Oxford University Press, 2024)Darwin and Bateman suggested that precopulatory sexual selection is more intense on males than females, and that this difference is due to anisogamy (i.e., dimorphism in gamete size and number). While a recent paper ... -
Coevolution of parental investment and sexually selected traits drives sex-role divergence
Fromhage, Lutz; Jennions, Michael D. (Nature Publishing Group, 2016)Sex-role evolution theory attempts to explain the origin and direction of male-female differences. A fundamental question is why anisogamy, the difference in gamete size that defines the sexes, has repeatedly led to large ... -
Simultaneous age-dependent and age-independent sexual selection in the lekking black grouse (Lyrurus tetrix)
Kervinen, Matti; Lebigre, Christophe; Soulsbury, Carl D. (Wiley-Blackwell Publishing Ltd.; British Ecological Society, 2016)Individuals' reproductive success is often strongly associated with their age, with typical patterns of early‐life reproductive improvement and late‐life senescence. These age‐related patterns are due to the inherent ... -
