From: African KhoeSan ancestry linked to high-risk prostate cancer
a Ancestral fractions determined using STRUCTURE analysis 84 South African Coloured men with PCa using 114,199 autosomal markers and K = 4 (5000 burn in and 10,000 reps) identifying ancestral contributions defined as African-KhoeSan, African-Bantu, European and Asian. b Magnitude and origin of migrants is shown with different colors in bar and pie charts representing three ancestral contributions. The size of pie charts is proportional to percentage of migrants, with the earliest generation equal to 100% and a decrement in the next generation
