Figure 2 From: Sequence variation in human succinate dehydrogenase genes: evidence for long-term balancing selection on SDHA Tajima's D statistic and nucleotide diversity in SDHA and SDHB genes (squares) relative to the 282 genes in SeattleSNP database are shown in the African American population. Positions of two highly polymorphic loci, ABO and FUT2, the latter of which encodes the alpha(1,2)fucosyltransferase, are shown.Back to article page
