ABSTRACT

Data for individual females of Drosophila prosaltans concerning 16 fitness components were analysed to verify the neutral and the adaptive hypothesis of fitness components to Darwinian fitness. Significant correlations between fitness components and Darwinian fitness and the principal components analysis results showed a differential importance of the components studied.

Keywords: Darwinian fitness.
