"Webpersistent individuals in African and European populations have large regions of homozygosity around the lactase-persistence alleles. Each blue and green bar represents a region of homozygosity in one individual; the lengths of these regions are shown at the bottom of the figure. Large areas of homozygosity indicate strong, recent selection. " - How many alleles does a gene have
