“…To summarize, there is a lack of consensus on the speed of resolution, with the precise detail of G and B likely to be taxon specific (e.g. [ 49 , 50 ]), and their effects also influenced by the strength of sex-specific selection. Meaningful measures of sex-specific selection and a better understanding of the genetic variance–covariance matrix will aid predictions of the evolution of sexual dimorphism.…”

Anisogamy, different-sized male and female gametes, sits at the heart of sexual selection and conflict between the sexes. Sperm producers (males) and egg producers (females) of the same species generally share most, if not all, of the same genome, but selection frequently favours different trait values in each sex for traits common to both. The extent to which this conflict might be resolved, and the potential mechanisms by which this can occur, have been widely debated. Here, we summarize recent findings and emphasize that once the sexes evolve, sexual selection is ongoing, and therefore new conflict is always possible. In addition, sexual conflict is largely a multivariate problem, involving trait combinations underpinned by networks of interconnected genes. Although these complexities can hinder conflict resolution, they also provide multiple possible routes to decouple male and female phenotypes and permit sex-specific evolution. Finally, we highlight difficulty in the study of sexual conflict over shared traits and promising directions for future research.
