  bibo_abstract:
  - Behavioural variation among conspecifics is typically contingent on individual
    state or environmental conditions. Sex-specific genetic polymorphisms are enigmatic
    because they lack conditionality, and genes causing adaptive trait variation in
    one sex may reduce Darwinian fitness in the other. One way to avoid such genetic
    antagonism is to control sex-specific traits by inheritance via sex chromosomes.
    Here, controlled laboratory crossings suggest that in snail-brooding cichlid fish
    a single locus, two-allele polymorphism located on a sex-linked chromosome of
    heterogametic males generates an extreme reproductive dimorphism. Both natural
    and sexual selection are responsible for exceptionally large body size of bourgeois
    males, creating a niche for a miniature male phenotype to evolve. This extreme
    intrasexual dimorphism results from selection on opposite size thresholds caused
    by a single ecological factor, empty snail shells used as breeding substrate.
    Paternity analyses reveal that in the field parasitic dwarf males sire the majority
    of offspring in direct sperm competition with large nest owners exceeding their
    size more than 40 times. Apparently, use of empty snail shells as breeding substrate
    and single locus sex-linked inheritance of growth are the major ecological and
    genetic mechanisms responsible for the extreme intrasexual diversity observed
    in Lamprologus callipterus.@eng
