【 摘 要 】

Mate choice in female Apistogramma cacatuoides is genetically determined. Females of the aquarium strain studied have a strong preference for red-coloured males of their own strain, although some deviate from this basic sexual preference, and those which choose redcoloured males in a first mate-choice experiment may subsequently choose males of a different strain. Where fry were raised by parents of a different strain in cross-fostering experiments, the mate choice of females raised in this way differed significantly from that of females raised by their own parents. This indicates a clear influence of learning on the basic genetically determined mate preference. The implications of these findings are discussed in the context of speciation.
