Blood group B has its highest frequency in Northern India and neighboring Central Asia, and its incidence diminishes both towards the west and the east, falling to single digit percentages in Spain.[31][32] It is believed to have been entirely absent from Native American and Australian Aborigines populations prior to the arrival of Europeans in those areas.[32][33]

Blood group A is associated with high frequencies in Europe, especially in Scandinavia and Central Europe, although its highest frequencies occur in some Australian Aborigines populations and the Blackfoot Indians of Montana.[34][35]
