Figure 1. Population structure of the Luhya in Webuye, Kenya.
( A) Map of Africa showing the location of Kenya. ( B) Map of Kenya showing the location of Western Kenya Counties. ( C) The four Counties in Western Kenya inhabited by the “ Luhya people”. The 17 tribes of the Luhya, and the locations they hail from in Western Kenya are shown with numbers 1 through 17. ( D) The distribution of individuals from the LWK, YRI and MSL populations along the first three principal components. ( E) Ancestry for K value 5 for the Luhya (LWK) from Webuye, Kenya (n=99); Yoruba (YRI) from Ibadan, Nigeria (n=108); Esan (ESN) from Nigeria (n=99); Mandika (GWD) from The Gambia (n=113); and the Mende (MSL) from Sierra Leone (n=85)) examining the same 193,634 variants. The plot of ancestry fractions shows population sub-structure in the LWK population, when compared to five other populations from the 1000 Genomes Project (1000GP).
