CMMB 403 Question and answers already passed 2024Fertilization - correct answer Fusion of an egg and sperm cell to produce a zygote Cleavage - correct answer rapid mitotic cell division of the zygote that begins immediately after fertilization Gastrulation - correct answer In animal development, a series of cell and tissue movements in which the blastula-stage embryo folds inward, producing a three-layered embryo, the gastrula. Organogenesis - correct answer process of organ format...

Which animal's development is chick development most similar to compared to other species?Most similar to humans than other species talked about in lecture (like amphibians and flies) What is the Nieuwkoop Centre (NC)? When does it emerge during embryo development?Centre that induces the formation of the organizer and later the dorsal mesoderm; emerges during the late blastula stage How does the fish organizer and Niewukoop Centre (NC) compare to their amphibian counterparts?They have si...
