Disruptive sexual selection on male nuptial coloration in an experimental hybrid population of cichlid fish.
Theory suggests that genetic polymorphisms in female mating preferences may cause disruptive selection on male traits, facilitating phenotypic differentiation despite gene flow, as in reinforcement or other models of speciation with gene flow. Very little experimental data have been published to test the assumptions regarding the genetics of mate choice that such theory relies on. We generated ...
متن کاملDifferences in male coloration are predicted by divergent sexual selection between populations of a cichlid fish.
Female mating preferences can influence both intraspecific sexual selection and interspecific reproductive isolation, and have therefore been proposed to play a central role in speciation. Here, we investigate experimentally in the African cichlid fish Pundamilia nyererei if differences in male coloration between three para-allopatric populations (i.e. island populations with gene flow) of P. n...
متن کاملInheritance of female mating preference in a sympatric sibling species pair of Lake Victoria cichlids: implications for speciation.
Female mate choice has often been proposed to play an important role in cases of rapid speciation, in particular in the explosively evolved haplochromine cichlid species flocks of the Great Lakes of East Africa. Little, if anything, is known in cichlid radiations about the heritability of female mating preferences. Entirely sympatric distribution, large ecological overlap and conspicuous differ...
متن کاملInteraction between female mating preferences and predation may explain the maintenance of rare males in the pentamorphic fish Poecilia parae.
Variation in mating preferences coupled with selective predation may allow for the maintenance of alternative mating strategies. Males of the South American live-bearing fish Poecilia parae fall in one of five discrete morphs: red, yellow, blue, stripe-coloured tail (parae) and female mimic (immaculata). Field surveys indicate that the red and yellow morphs are the rarest and that their rarity ...
متن کاملThe genetics of mate preferences in hybrids between two young and sympatric Lake Victoria cichlid species.
The genetic architecture of mate preferences is likely to affect significant evolutionary processes, including speciation and hybridization. Here, we investigate laboratory hybrids between a pair of sympatric Lake Victoria cichlid fish species that appear to have recently evolved from a hybrid population between similar predecessor species. The species demonstrate strong assortative mating in t...
