The experimental design employed for this purpose was based on 4 general assumptions. The results reported in the present study allow US to verify 3 of these assumptions i mating is at random irrespective of the flies karyotype ii gametic selection may be considered absent and iii there is no differential attraction of flies to the collecting baits. The validity of these assumptions gives strong support to the conclusions reached in our previous selection components analysis. mating pattern gametic selection chromosomal polymorphism Résumé Le polymorphisme du deuxième chromosome de Drosophila buzzatii dans une population naturelle n est pas associé à une selection gamétique et n affecte pas le mode d accouplement. Dans un travail precedent nous avons démontré la signification adaptative du polymorphisme chromosomique de D buzzatii dans une population naturelle d Argentine à I aide d une analyse de la selection en ses composantes. Le plan d experience utilise dans ce but était base sur quatre hypotheses. Les résultats présentés dans le present travail permettent la verification de trois d entre elles i I accouplement se produit au hasard indépendamment du .
