The anterior-posterior and dorsal-ventral axes have a common origin in Drosophila melanogaster.
The mechanisms governing anterior-posterior and dorsal-ventral polarity in Drosophila melanogaster had previously been considered as independent processes. However, two papers(1,2) now reveal that both axes are initiated during oogenesis by the same pathway, and also clearly demonstrate that one is dependent on the other.
