Gachon-Phlyogeny

 Genetic ancestry

The Y chromosomal haplotype data from Y Chromosomal Consortium (YCC) were applied to draw the paternal linage tree. 

The mitochondiral haplotype linage tree was drawn with XXXX.

Allele Sharing Distance and Neighbor Joining method were applied to the autosomal linage tree (Mountain and Cavalli-Sforza, 1996; Bowcock et al, 1994). XXXX number of markers shared in the personal genomes and HapMap phase III genotypes of three populations ? Yoruban (YRI), CHB (Chinese), CEU (Caucasian), and JPT (Japanese) were applied.

ASD was calculated as follows,

The proportion(P_i ) of shared alleles between individuals could be estimated by

        P_i = ΣuS / 2u                                                      --- 1)

 Where the number of shared alleles S is summed over all loci u.

Distance between individuals (D_i ) is estimated by, 

      D_i = 1 - P_i                                                           --- 2)
