Objective
To expose students to various aspects of genetic diversity, its measurement, grouping and study of phylogenetic relationship

UNIT I
The meaning of diversity, history, importance and its use in agriculture. Assessment of diversity: Morphological, biochemical and molecular.

UNIT II
Statistical techniques for measuring diversity: Measures of quantitative and qualitative variability, diversity indices; and methods for marker data analysis. Statistical techniques for clustering: Hierarchical and non-hierarchical cluster analysis, algorithms for forming clusters/ dendrograms, data transformation and choice of scales, exposure to various clustering softwares.

UNIT III
Evolution and Diversity: Phylogenetics, concept of  evolutionary trees, rooted and unrooted topology, methods for studying phylogeny-maximum, parsimony, distance methods, maximum likelihood, reliability of  prediction. Exposure to various softwares (MEGA, Phylip. NTSYS etc.)
