(A) Geographic distribution of African (green), (B) European (blue), (C) Amerindian (orange) ancestry based on individual estimates.
To facilitate comparison, color intensity transitions occur at 10% ancestry intervals for all maps. Maps were obtained using Kriging interpolation (see Materials and Methods).
Fig 3.
Dirichlet distributions of the ancestral components of the study population.
The European component had a normal distribution and consisted of 40–60% of the study population. The African component had a non-normal distribution and consisted of less than 30% of the study population. The Native American (Amerindian) component had a non-normal distribution and consisted of 20% of the study population.
