Course objectives:
This course will enable the students to –
1. Develop an understanding of scope and historical background of developmental biology to the students, impart knowledge regarding basic concepts of differentiation, morphogenesis and pattern formation and stem cells.
2. Analyze and demonstrate essential events of developmental biology through proper explanation of gametogenesis, and stages of embryonic development and fetal formation and anomalies associated with the development.

Gene Differen tiation & Gamete Biology

(Theory)

CO145.  Examine  developmental

patterns in unicellular eukaryotes

and    metazoans and develop an

understanding about the process of

gamete formation from stem cell

population to

mature ova and sperm.

CO146.   Appraise   the    detailed

knowledge of steps leading to the

formation of gametes and development of embryos.

CO147. Describe the mechanisms underpinning cell specification in animals and germ cell determination and migration.

CO148. Discuss axis specification

in     drosophila,    tetrapod    limb

development and metamorphosis in

amphibian and insects

CO149.      Analyze      the      sex

determination  in  mammals  and

process of teratogenesis.
