It has been claimed that in competitive conditions larval viabilities of Drosophila melanogaster depend on the similarity of genotypes coexisting. Two types of experimental populations were established: homogeneous (low genotypic variability) and heterogeneous (high genotypic variability). Under conditions of moderate larval competition productivity was similar, in each although the developmental time was shorter in the heterogeneous series. Under conditions of high larval competition the productivity of heterogeneous populations exceeded that of the homogeneous and attained the adult stage in shorter period of time.
有人声称，在竞争条件下，黑腹果蝇幼虫的活力取决于共存基因型的相似性。建立了两种类型的实验种群：同质种群（基因型变异性低）和异质种群（基因型变异性高）。在适度幼虫竞争条件下，尽管异质种群系列的发育时间较短，但每个种群的生产力相似。在高幼虫竞争条件下，异质种群的生产力超过了同质种群，并在更短的时间内达到成虫阶段。
