Key Findings
The evolutionary tree analysis shows the sequential occurrence of characteristics mutations in the B.1.1.7 variant. B.11.7 (deletion) and B.1.1.7 like (without deletion) from nine different regions were compared to examine the role of the non-coding deletion (g.a28271) in enhancing variant transmissibility.

Phylogenetic studies showed that VOC had unusual accumulation of substitutions in its genome and higher growth rate compared to other circulating lineages which is more due to increased transmissibility (R) rather than shorter generation time(shorter incubation period).
