Additional file 16: Figure S10 of Variation in NAT2 acetylation phenotypes is associated with differences in food-producing subsistence modes and ecoregions in Africa

Plot of the number of alleles (distinct NAT2 sequence haplotypes) of each functional category (green for slow, brown for fast, orange for unknown) observed in samples as a function of sample size. The dashed lines show the linear regression of number of haplotypes on sample size, and Pearson’s product–moment correlation coefficients are provided in the top-left caption. (PDF 2 kb)
