Drosophila females exhibit gregarious oviposition. This behaviour was analysed by a diallel cross. The trait shows considerable additive genetic variation and a significant dominant effect. A variance and covariance analysis suggests that ebony and taxi strains contain the most dominant alleles. Some maternal effect may also be present. This genetical architecture is in line with previous studies of selection and hybridization of the lines selected for high and low gregarious oviposition in Drosophila melanogaster females.
果蝇雌性表现出群居产卵行为。通过双列杂交对这种行为进行了分析。该性状显示出相当大的加性遗传变异和显著的显性效应。方差和协方差分析表明,乌木色和出租车品系含有最主要的等位基因。可能也存在一些母体效应。这种遗传结构与之前对黑腹果蝇雌性中为高群居产卵和低群居产卵选择的品系进行选择和杂交的研究一致。
