For Europeans and Americans of European descent, over 95% can be classed into nine main clans: H, I, J, K, T, U, V, W and X. For Africans, the 14 main clans are L0a, L0d, L0f, L1b, L1c, L2a, L2c, L3b, L3d, L3e, L3f, L3h, L3i, L4, L5. For East Asia, there are 11: Z, D, A, N, Y, F, R, B, C, E, G, M. For South Asian, there are nine: M, N, X, R, J, H, T, U, F. For Oceana, there are five : N, M, P, B, Q. For Native Americas, there are five: A , B, C, D and X. The non-redundant list has 38 haplogroups; with sub-haplogroups the number increases to over 150. It is important to note that these are arbitrary numbers – it is possible to define thousands of groups related by common descent, but that is too many to be useful for classification purposes.
