In very few regions of Africa are the blood group distributions known in detail—even for the ABO system—and the maps must therefore be treated with reserve. Small-scale maps are useful for showing general trends, such as the rise in O frequency from the Middle East to Central Africa, but they cannot do justice to the considerable local fluctuation which detailed surveys have revealed (especially in Liberia and in the Eastern Congo).
