Statistical analysis for estimating heterogeneity of the Korean population in DNA typing using STR loci

The coancestry coefficients for the Korean population are estimated by using 3 statistical methods for 17 loci (D3S1358, D21S11, D13S317, D18S51, D7S820, D8S1179, D5S818, FGA, VWA, F13A1, FES/FPS, THO1, TPOX, CSF1PO, D12S391, GABA and ACTBP2). The subpopulations were considered by last name and home origin, respectively. Our results show that the values for the coancestry coefficient for the Korean population are too large to ignore although they do not show substantial heterogeneity. These estimated values are also applied to simulated forensic cases.
