Schematic of the SARS-CoV-2 Omicron 21L/BA.2-21K/BA.1 recombinant genomes (a, b) and phylogeny reconstruction based on SARS-CoV-2 Omicron 21L/BA.2 and Omicron 21K/BA.1 genomes (c, d).

a. Map of the SARS-CoV-2 genome.

b. Schematic representation of parental and recombinant genomes and mutations in the recombinant genomes. Adapted from screenshots of the nextclade web application output (https://clades.nextstrain.org) (Aksamentov et al., 2021; Hadfield et al., 2018). Color codes for nucleotide mutations are as follows: Green: U; yellow: G; blue: C; red: A; light grey: deletions; dark grey: regions uncovered by sequencing reads.

c, d. Phylogeny reconstructions based on the whole genomes (c) or only on the region of these genomes that corresponds to the region of the recombinant genome that originates from the Omicron 21L/BA.2 variant. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
