Gene Differentiation & Gamete Biology

 

Students will :

CO120: Differentiate and evaluate  about the levels of organization among different groups of vertebrates and understand that different organs and organ systems integrate to impart proper regulation of a particular function

CO121: Develop an understanding about the process of gamete formation from stem cell population to mature ova and sperm.

CO122: Appraise the detailed knowledge of steps leading to the formation of gametes and development of embryos.

CO123: Describe the mechanisms underpinning cellular diversity and specificity in animals.

CO124: Analyse and demonstrate the process of Morphogenesis and Teratogenesis.
