A joint index for the intensity of sex-specific selection
journal contribution
posted on 2023-06-08, 12:31 authored by Paolo Innocenti, Ted MorrowA growing body of experimental and field data shows that selective pressures often differ between males and females. Surprisingly,to date, little attempt has been made to formalize a metric expressing the relative behavior of directional selection in the two sexes. We propose an index that describes the extent to which concordant or antagonistic selection is operating between the sexes for a given trait. This joint index could prove especially useful for the study of intralocus sexual conflict and the evolution of sexual dimorphism, providing a common scale to directly compare different traits within or among taxonomic levels, and allowing an assessment on how common sexually antagonistic selection might be in extant populations.
