DESCRIPTION OF COURSES
BI 527 PHYLOGENETIC ANALYSIS (1L+1P) II
To find out the evolutionary relationship among various species by using different phylogenetic algorithms.
Phylogenetic trees and their comparison: Definition and description, various types of trees; Consensus (strict, semi-strict, Adams, majority rule, Nelson); Data partitioning and combination. Tree to tree distances, similarity; Phylogenetic analysis algorithms: Maximum Parsimony, Distance- based: UPGMA, Transformed Distance, Neighbors-Relation, Neighbor-Joining.
Probabilistic models of evolution, Maximum likelihood algorithm ; Approaches for tree reconstruction: Character optimization; delayed and accelerated transformation, Reliability of trees, Bootstrap, jackknife, decay, randomization tests; Applications of phylogeny analyses: Comparison of Phylogenetic Trees obtained using DNA seq. Vs. protein seq. Vs. Full genomes. Need for addition of other properties towards total phylogenetic analysis, Comparative methods for detection of species / organism relationships, Gene duplication, Horizontal transfer, Domain evolution, Study of co-evolution: Plant-insect interactions. Host-parasite interactions, Viral evolution.
