Biosystematics, Taxonomy & Evolution

CO108:     Building     the                 basic

concepts of animal taxonomy and

analyze     the    implications               of

Chemotaxonomy,  Cytotaxonomy

and Molecular taxonomy

CO109: Analyze the Concept of

Molecular      Phylogenetics                   and

Genetics of Quantitative traits in

a population.

CO110:   It  would  furnish  the

student with different taxonomic procedures including taxonomic Collection, species concept and

Speciation, preservation

CO111:       Explain                   different

theories           of                      biological

classification     and    the                       basic

concept of the International Code

of     Zoological        Nomenclature

(ICZN).

CO112: Predict Molecular

analysis of quantitative traits
