Construction of Evolutionary tree Using MEGA
MEGA, Molecular Evolutionary Genetics Analysis, is a
freely available software for conducting statistical analysis of
molecular evolution and for constructing phylogenetic trees.
MEGA is an integrated tool for conducting :
• Sequence alignment,
• Inferring phylogenetic trees,
• Estimating divergence times,
Introduction
Conti……..
• Estimating rates of molecular evolution,
• Inferring ancestral sequences,
• Testing evolutionary hypotheses.
MEGA is used by biologists in a large number of laboratories for
reconstructing the evolutionary histories of species and inferring the extent and
nature of the selective forces shaping the evolution of genes and species
