Geography mostly shapes human genetic variation | Office of the These historical figures were pioneers in the study of human variation. The small fraction of DNA that varies among people can help explain differences in susceptibility to disease, response to drugs or reaction to environmental factors. Many genes are not polymorphic, meaning that only a single allele is present in the population: the gene is then said to be fixed. Genetic data also provide useful information about the origins and histories of individual human populations. Genetic variation, the genetic difference between individuals, is what contributes to a species' adaptation to its environment. Since then, each new genome sequenced and each new individual studied has illuminated our genomic landscape in ever more detail. Rank.
