Figure 2. — Genetic diversity and distribution of the B.1.1.28, Gamma, and Gamma-like lineages in Brazil. (A) ML phylogenetic tree of the B.1.1.28, Gamma, and Gamma-like lineages identified in Brazil. Each lineage was highlighted with colored boxes as indicated in the legend. The SH-aLRT support values are indicated in key branches, and branch lengths are drawn to scale with the lateral bar indicating nucleotide substitutions per site. Nodes representing the MRCA of each lineage and the MRCA of all Gamma and Gamma-related viruses (P.1_MRCA1), and the MRCA of Gamma and Gamma-like-II (P.1_MRCA2) are highlighted with circles. (B) Correlation between the sampling date of B.1.1.28, Gamma, Gamma-like-I, and Gamma-like-II and their genetic distance from the ML phylogenetic tree’s root. Each lineage was colored following the legend. The slope of each regression is indicated. (C) Geographic distribution and frequency of the Gamma-like-II lineage identified in Brazil. Brazilian states’ names follow the ISO 3166-2 standard. Color’s gradient represents the number of sequences identified in this study.
