Quizplus · Accepted Answer

Sperm nucleus is not a source of regulatory signals in animal development. While it does contribute genetic material to the developing embryo, it does not play an active role in the regulation of cellular processes during embryonic development. The other options, oocyte cytoplasm, nearby cells, and extracellular matrix, all contribute to the regulation of embryonic development through various signaling pathways and interactions with developing cells.
