Heatmap from Scientific Research

Heatmap showing recombination-corrected SNP distance between pairs of M catarrhalis genomes, with each small square representing a different genome. Evidence of probable (0–10 SNPs) and possible (10–100 SNPs) strain sharing in mother–infant pairs from the same family (green and blue, respectively) and from different families (red and orange, respectively; dashed red line used for non-adjacent sequences); and between related sibling-infant pairs (pink, 0–10 SNPs). B=breastmilk. C=child younger than 5 years (sibling). I=infant. M=mother. M catarrhalis=Moraxella catarrhalis. N=nasopharynx. O=oropharynx. S=saliva. SNP=single nucleotide polymorphism.
