This is most likely a problem of A) morphogenesis. B) cell differentiation. C) histogenesis. D) preformation. E) fertilization. Answer: A Topic: Overview Skill: Application 4) As an embryo develops, new cells are formed and different types of cells develop by the process of A) differentiation and morphogenesis.
