Question
Chapter 51, Problem 8TYU
Summary Introduction
Introduction: During the process of embryonic development, the zygote undergoes multiple divisions to give rise to the embryo. The embryo undergoes several divisions to mature into the adult organism. The gastrula has three germ layers, namely ectoderm, mesoderm, and ectoderm.
