Fig. 4From: The geno-spatio analysis of Mycobacterium tuberculosis complex in hot and cold spots of Guangxi, ChinaThe frequency distribution of SNPs distances in hot and cold spot areas. In general, SNP distance peak of > 1000 are form differences between isolates belonging to different lineages, in this case between L2 and L4. 500–1000 are resulted from major sub-lineages such as between L2.1 and L2.2. The ones < 500 are usually from differences between more detailed sub-lineages such Asian African2 and Asian African 3. < 100 is almost definitely from the difference between isolates belonging to the same detailed sub-lineages or the same clusterBack to article page
