[Geographic distribution maps of human genes in China].

The first set of geographic distribution maps of human gene in China are published, including 12 alleles: IB and IO of ABO system, m of MNS system, P1, Rh-D, A1 and A11 of HLA system, Gm1;21 and Gm1,3;5 of immunoglobulin, AK1, deficient type of G6PD, and PTC test blindness gene t. These maps not only show the geographic distribution of alleles, but also can be used to study the origin and dispersal of some alleles, gene flow, and the effect of some selective factors on gene frequencies.
