Number of people detecting a soapy taste by ancestry group, sorted from most to least soapy-taste detection. For reference, we have added the minor allele frequency of rs7107418 in each group. This SNP is a proxy for rs72921001 (r² > 0.98), with the minor G allele of rs7107418 corresponding to the minor A allele of rs72921001 (which is associated with less soapy tasting). The p value is the p value of association between soapy-taste and rs7107418 in each group.
