Ancestry-informative markers are sets of polymorphisms for a particular DNA sequence that appear in substantially different frequencies between populations from different geographical regions of the world. Ancestry-informative markers can be used to estimate the geographical origins of the ancestors of an individual typically by continent of origin (Africa, Asia, or Europe).
