High-ranking males have more access to fertile females and consequently partake in most of the matings within the group; in one population, three males were responsible for over 75 of matings. 26 In an effort to determine if JH is indeed responsible for manifesting dominance, a follow up experiment was done utilizing 20-hydroxyecdysone, an ecdysone known to enhance maturation and size of oocytes. The social order can be either egalitarian or despotic. 46 In some ant species such as the carpenter ant Camponotus floridanus, eggs from queens have a peculiar chemical profile that workers can distinguish from worker laid eggs.

Brood hierarchy edit The blue-footed booby brood of two chicks always has a dominance hierarchy due to the asynchronous hatching of the eggs. Wildlife Behavior and Conservation. 27 The results showed that the 20-hydroxyecdysone treated foundresses showed increased dominance compared to those foundresses treated with JH and suggests that 20-hydroxyecdysone, not JH may play a larger role in establishing dominance (Roseler., 1984).
