Constructing Phylogenetic Tree using MEGA Software

A phylogenetic tree ( a.k.a. , cladogram or dendrogram) is a diagrammatic/graphical representation of the genetical/evolutionary relationship of species/organisms/genes. It helps to find the common ancestor. Construction of a phylogenetic tree consists of two phases, multiple sequence alignment and computing distance matrix. This is a simple video tutorial for constructing a phylogenetic tree using Molecular Evolutionary Genetics Analysis ( MEGA ) software. The MEGA software produces phylogenetic trees from multiple sequences in various formats: rectangular, slanting, curved, radial, and curved.
