Textbook Question
Textbook QuestionEarly development in Drosophila is atypical in that pattern formation takes place in a syncytial blastoderm, allowing free diffusion of transcription factors between nuclei. In many other animal species, the fertilized egg is divided by cellular cleavages into a larger and larger number of smaller and smaller cells.
What constraints does the formation of a syncytial blastoderm impose on the mechanisms of pattern formation?
