The evolutionary divergence over sequence pairs between populations of Heterotrigona itama were estimated.

The number of base substitutions per site from averaging over all sequence pairs between populations were estimated using Kimura 2-parameter model (Kimura, 1980) and shown. Population abbreviations as in S1 Table.

本研究采用木村双参数模型（Kimura 2-parameter model，Kimura, 1980），对种群间全部序列对的平均每位点碱基替换数进行估算，并将估算结果予以展示。种群缩写详见S1表。
