Quizplus · Accepted Answer

The regulation that determines the anterior and posterior ends of a developing Drosophila embryo is primarily spatial, as it is based on the differential localization of morphogens such as bicoid and nanos mRNA in the egg. Maternal vs paternal translation is not a factor in this process, and while transcriptional regulation is important for overall development, it does not determine the anterior-posterior axis. Temporal regulation may play a secondary role in axis determination, but is not the primary mechanism.
