Genetics doi:10.1007/s00439-010-0836-1 Genome-wide analysis of
the structure of the South African Coloured Population in the
Western Cape Erika de Wit et al. Admixed populations present
unique opportunities to discover the genetic factors underlying
many multifactorial diseases. The geographical position and
complex history of South Africa has led to the establishment of
the unique admixed population known as the South African
Coloured. Not much is known about the genetic make-up of this
population, and the historical record is patchy. We genotyped
959 individuals from the Western Cape area, self-identified as
belonging to this population, using the Affymetrix 500k
genotyping platform. This resulted in nearly 75,000 autosomal
SNPs that could be compared with populations represented in the
International HapMap Project and the Hu
