Maximum likelihood tree of the SARS-CoV-2 sequences. A maximum likelihood tree was built for the sequences retrieved in our study along with other GISAID sequences from Uttar Pradesh, India using the best substitution model. A bootstrap replication of 1,000 cycles was performed to assess the statistical robustness. SARS-CoV-2 sequences retrieved in the study are marked in bold black color. The nodes and branches are marked in different colors.
