GENETIC DIVERSITY OF OMICRON SUBLINEAGES

Abstract

The haplotype diversity (Hd) parameter of the BA.1 sublineage is 1,170, which is 0.750 higher than that of the BA.2 sublineage and the BA.3 sublineage is 0.408. Therefore, the haplotype diversity of the BA.1 sublineage is the largest, followed by the BA.2 sublineage, and the BA.3 sublineage is the lowest. The nucleotide diversity parameters of the BA.1 sublineage is the largest p₁=0.00053, q_S1=0.00053, q_seq1=2,103 and k₁=2.26, followed by the BA.2 sublineage p₂= 0.00033, q_S2=0.00024, q_seq2=0.736 and k₂=1.05, the smallest being the BA.3 sublineage p₃=0.0010, q_S3=0.00013, q_seq3=0.480 and k₃ =0.42. Therefore, the BA.1 sublineage has the greatest nucleotide diversity, followed by the BA.2 sublineage and the BA.3 sublineage is the lowest. Thus, the BA.1 sublineage has the greatest genetic diversity, the second is the BA.2 sublineage and the BA.3 sublineage is the lowest. The BA.1 sublineage is the original lineage that evolved into sublineages BA.2 and BA.3
