Biosystematic, Taxonomy & Evolution

Students will

CO1: Building the basic concepts of animal taxonomy and analyze the implications of Chemotaxonomy, Cyto-taxonomy and Molecular taxonomy

CO2: Analyse the Concept of Molecular Phylogenetics and Genetics of Quantitative traits in a population.

CO3: It would furnish the student with different taxonomic procedures including taxonomic collection, species concept and Speciation, preservation, methods of identification and taxonomic keys.

CO4: Explain different theories of biological classification and the basic concept of the International Code of Zoological Nomenclature (ICZN).

CO5: Predict Molecular analysis of quantitative traits
