Definition and basic concepts of biosystematics and taxonomy
Importance and applications of bio-systematic in biology
Material basis of biosystematics-different attributes
Trends in biosystematics- Chemotaxonomy, Cytotaxonomy, Molecular taxonomy
Dimensions of speciation and taxonomic characters
Dimensions of speciation – types of lineage changes, production of additional lineage
Theories of Biological classification, Hierarchy of categories
Species concept- Species category, different species concept, subspecies and other infra specific categories
Mechanisms of speciation in panmictic and apomictic species
Taxonomic characters – different kinds, origin of reproductive isolation
Procedure keys in taxonomy
Taxonomy procedures-Taxonomic collections, preservations, curetting process of identification
Taxonomic keys-Different kinds of Taxonomic keys, their merits and demerits
Systematic publication-Different kinds of publications
Process of typification and different zoological types
International code of Zoological nomenclature (ICZN) – its operative principles, interpretation and application of important rules, Zoological nomenclature, formation of scientific names of various taxa.
Evaluation of biodiversity indices: Shannon-Weinner index, dominance index
Concept of evolution and theories of organic evaluation with an emphasis on Darwinism.
Micro and Macro-evolution
Neo-Darwinism
Hardy –Weinberg law of genetic equilibrium Detailed account of Destabilizing forces:
- Natural selection
- Mutation
- Genetic drift
- Migration
- Meiotic drive
Genetics of quantitative traits in populations
Analysis of quantitative traits
Genotype-environment interactions
Inbreeding depression and heterosis
Molecular analysis of quantitative traits
Phenotypic plasticity
Molecular phylogenetics
How to construct phylogenetic trees
Phylogenetic inference-Distance methods, parsimony methods, maximum likelihood method
