In previous work we have demonstrated the adaptive significance of thechromosomal polymorphism of D buzzatii in a natural population from Argentina by meansof selection components analysis. The experimental design employed for this purpose wasbased on 4 general assumptions. The results reported in the present study allow us toverify 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 attractionof flies to the collecting baits. The validity of these assumptions gives strong support tothe conclusions reached in our previous selection components analysis.
