Explain how the embryo forms from the zygote
After an egg is fertilized, and has fused with sperm to form a zygote, an embryo begins to develop. The process in which an organism develops from a single-celled zygote to a multi-cellular organism is complex and well-regulated. The early stages of embryonic development are also crucial for ensuring the fitness of the organism.
