"WebHuman genetic variation is clinal, which means that variation develops gradually and continuously over spatial gradients [41]. No one gene, pattern of genes, region of DNA, or set of “ancestral informative markers” reliably determines race [42]. Certain variants have been found to be more common in some groups than in others [43]. " - Human variation is clinal
