Phylogenetic analysis has developed as a piece of significant equipment throughout biology for correlating data and information about genes, individuals, populations, and species. This evidence is usually in the pattern of morphological, behavioral or molecular data, and phylogenetic analysis is utilized to assess the historical connections among the genes or species and to illustrate these associations in the structure of a branching diagram, known as a phylogenetic tree. Apart from the conventional practice of phylogeny in evolutionary biology, there has been an increasing fulfilment of the need for phylogenetic analysis in any research in which biological fluctuation is described regarding samples. The requirement for phylogenetic analysis ensues from the fact that the objects of study, usually called taxa, whether they are genes, species, or some other level of organization, are not statistically independent, but are associated through historical relationships. Any factual statistical version of the patterns of biological deviation among taxa requires an estimate of such historical relationships. Please go through the attached PPT for details.
