Genetic Studies conducted on full-blooded indigenous populations from North, Central, and South America (the New World) has identified a limited number of shared genetic markers. These markers have very specific modes of inheritance and are relatively unique to populations with Native American Ancestry. There are 2 types of inheritance pattern categories that these markers follow, either a directly paternal linkage (i.e., male-to-male-to-male, etc.) or a directly maternal linkage (i.e., female-to-all her children. Then, only the female children pass it on to all their children)
