[The dynamics of embryonic mortality in inbred Drosophila strains]

This paper describes embryonic mortality in selected inbred strains of Drosophila studied over time. We found that the incidence rate of nondeveloping eggs increases up to 100% during the first 4 days after oviposition in the strain selected for high embryonic mortality (HEM). We have analyzed the contribution of both sexes to the realization of this effect and possible mechanisms of its appearance.
