It has been shown previously that a polymorphism for two alleles of the ref(2)P locus is a regular feature of French natural populations of Drosophila melanogaster and that this is maintained in laboratory populations raised in cages. In this paper, an experimental population and egg-collection experiments are reported. Differential survival of the three genotypes would be the main factor leading to the equilibrium frequencies, working only in drastic conditions of larval competition.
先前已经表明,ref(2)P基因座两个等位基因的多态性是法国黑腹果蝇自然种群的一个常见特征,并且在笼养的实验室种群中也得以维持。本文报道了一个实验种群和采卵实验。三种基因型的差异存活将是导致平衡频率的主要因素,仅在幼虫竞争的极端条件下起作用。
