In this work, 45 Spike glycoprotein Chain B polypeptides were used in the subvariants BA.2.12.1, BA.4 and BA.5 were recovered from GENBANK. All sequences were publicly available on the National Biotechnology Information Center (NCBI) platform. The results indicate the existence of informative polymorphic and parsimony sites that may be implicated in the level of diversity of the studied strains, as well as reflect the immunological evasion potential of the subvariant BQ1.1. of the variant Omicron d and SARS-CoV-2. The results also suggest the formation of ancestral polymorphism with slight retention, and the probable is responsible the diversity of the whole studied set.
