Abstract:
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.
