Timing of gene expression during embryogenesis in C. capitata and D. melanogaster. A schematic representation of the medfly and D. melanogaster embryogenesis stages, from oviposition (0 h) to hatching (48 h in the medfly, 24 h in D. melanogaster). The zygotic expression onset of crucial genes of the sex determination cascade and the two zygotic expression waves are reported in both species.
