Abstract
Maternal hunchback activity suppresses the genetic pathway for abdomen formation in the Drosophila embryo. The active component of the posterior group of maternal genes, nanos, acts as a specific repressor of hunchback in the posterior region. Absence of both repressors results in normal embryos, indicating that posterior segmentation may not directly require maternal determinants.Keywords
