Embryonic development time for 43 DGRP strains. n indicates sample size (= number of embryos measured individually from egg laying until emergence of the first instar larva; non-viable and retain eggs are not included). Embryonic DT is the obtained raw duration of embryogenesis measure, while Rel. med. DOE is the relative measure (standardized with the reference strain). Egg viability was calculated as the ratio of hatched eggs and the total number of eggs transferred to the imaging plate. Non-viable eggs contain both unfertilized eggs and embryos that failed in their embryonic development. Values resulted in from three independent replicates, and in one case only two replicates (*)
