Allele frequencies and concurrence of OR mutations within human populations. The number and frequency distribution of natural variants from seven sub-continental populations obtained from gnomAD and corresponding to a Ashkenazi Jewish (ASH), b European Finnish (EF), c East Asian (EA), d African (AFR), e Latino (LAT), f South Asian (SA), and g European non-Finnish (ENF). Bars are colored according to the allele frequency scale on the right. h Circos plot of the concurrence of mutations between populations. The width of the link between two populations corresponds to the number of shared mutations between them, also represented by a color gradient (numerical values are displayed on the right)
