This course introduces developmental processes leading to the establishment of body plans in metazoan organisms. It covers fertilization through developmental stages to organismal and postembryonic development. The course explores cellular and genetic mechanisms, gametogenesis, cleavage formation, gastrulation, invagination, and organogenesis. Students will learn about general embryology, embryonic membranes, and placenta formation, providing a comprehensive understanding of developmental biology.

Where it gets hard
The units students slow down on, and what makes each one heavy.
- Module 2: Gametogenesis
Unit 3: Mitosis and Meiosis
The complex processes of meiosis and the genetic implications of chromosome assortment and crossing-over require a strong understanding of genetics and cell biology.
- Module 4: Gastrulation, Invagination and Organogenesis Formation
Unit 1: Gastrulation and Invagination in major groups of organisms
Understanding the coordinated cell and tissue movements during gastrulation and the establishment of the three germ layers requires strong visualization skills.
