Dominance hierarchy is male-specific: it is not bi-(inter-)sexual or female.
Abstract
Dominance hierarchy (DH) is never bi-(inter-)sexual. Rare ostensible female dominance (over males) is not even amenable to modelling, and actually is male non-engagement in dominance terms (deference, not submission). Any female hierarchy is not DH, as it is not contest-based, but from either mutually signalled differential fecundity or maternal rank inheritance. Otherwise, apparent female hierarchy is either non-dominance-based first-among-equals -- winner-takes-all -- sociality of a female sole reproducer, or a loose artefact of ad hoc resource competition. DH entails neuro-hormonally processing winner/loser effects, for which there is evidence only in males, and requires the Y chromosome’s SRY gene. Male-specificity is anticipated from the male root function of genetic filtration / mutational cleansing, necessitating male ranking in terms of genomic integrity.
