Figure 7. Correlation between zinc deficiency state and frequency of putative selected haplotype.
(A) Estimated country-specific prevalence of zinc deficiency and worldwide haplotype frequency distribution for SLC30A9. Population zinc deficiency data are based on the composite nutrient composition database, IZINCG physiological requirements, the Miller Equation to estimate zinc absorption and an assumed 25% inter-individual variation in zinc intake (Ref. 20, see Table S3). (B) Correlation test for the zinc deficiency and frequency of Hap2. World map was created by R packages (http://www.r-project.org/).
