Who are your blood-type ancestors?

42% of people in the UK have blood type A. In Ireland 31% have blood-type A.

Interestingly there is a higher concentration of blood-type A on the East coast of Ireland as opposed to the West Coast. This is probably due to the historical influence of Viking, Anglo Norman and English settlements.

Contrary to what you may expect, the distribution differs in every corner of the globe according to many ethnic and racial analyses done throughout the years by the blood banks around the world. If your blood type is rare in your country, you can look for your worldwide ancestors on and see where you got that from.
