DEVELOPMENTAL BIOLOGY
Course Objectives:
This course will enable the students to
1. The course objective is to provide students with a basic understanding of how organisms maintain gamete population, fertilization process, way of cleavage and different patterns to form zygote.
2. Understand the organogenesis in chick, extra embryonic membranes, types & physiology of placenta, metamorphosis, apoptosis and teratogenesis.
