Evolution of body colouration in killifishes (Cyprinodontiformes: Aplocheilidae, Nothobranchiidae, Rivulidae): Is male ornamentation constrained by intersexual genetic correlation?

Popis výsledku v původním jazyce

Sexual selection drives the evolution of exaggerated traits in males of many animal species. Nevertheless, the response to this selective pressure can be constrained by genetic correlation between sexes. This hypothesis predicts that costly ornamental structures selected for only in males appear also in females, at least because both sexes share most of their genomes. If a trait bears no fitness advantages to females, its expression should reflect a compromise between selection for hypertrophy in malesand natural selection favouring reduction of ornamentation in females. Therefore, extravagant male ornaments should evolve predominantly under weak intersexual genetic correlation. Here, we explore the role and evolutionary stability of the constraint imposed by intersexual genetic correlation in the evolution of body colouration in three species-rich families of killifishes. Across most killifish lineages, the evolutionary changes in male and female variegation were correlated, which id
