GENETICS AND EVOLUTIONARY BIOLOGY

 

The students will be able to-

CO1: Assemble detailed knowledge about the patterns of Mendelian inheritance and interactions of Genes and their expressions.

 

CO 2: Compare the role of crossing over and linkage in heredity and cytoplasmic inheritance.

CO 3: Deduce the concept of chromosomes involved in sex determination

CO 4: Formulate how natural polymorphism and genetic variation can give rise to mutant genes, and how these genetic errors are inherited.

CO 5: Critically analyze the evidences that living species share descent from common ancestry and how this fact explains the traits of living species

 CO 6: Acquire knowledge on evolutionary changes, genetic composition of populations, variation, isolation, speciation and adaptation etc 

Approach in teaching: Discussion, Demonstration, Action Research, Project, Field Trip
