Construction of phylogenetic tree from NCBI retrieved SARS-CoV-2 genomes in GenBank format.
The tree was constructed from five viral sequences per continent or thirty sequences in total.
The selected sequences accession numbers (file: accessions.txt) were chosen from:
NCBI Virus Sequences Dashboard for SARS-CoV-2 .
For the construction of the phylogenetic tree, multiple sequence alignment of the SARS-CoV-2 genomic sequences was performed with Clustal Omega and the tree was created with the UPGMA (Unweighted Pair Group Method with Arithmetic Mean) algorithm, using a distance matrix calculated using the MSA.
