To analyze the genetic polymorphism of 6 short tandem repeat (STR) loci on chromosome 7p14-15 and 8 STR loci on chromosome 12q13 in Chinese north Hans. Fluorescence-labeling polymerase chain reaction and capillary electrophoresis were used to analyze the genetic polymorphism of 100 randomly selected individuals from Chinese north Han nationality at 6 STR loci (D7S1808, D7S2250, D7S2251, D7S683, D7S656 and D7S528) on chromosome 7p14-15 and 8 STR loci(D12S1056, D12S1293, D12S83, D12S1655, D12S1662, D12S334, D12S137 and D12S102) on chromosome 12q13. In the Chinese north Han population, 7 alleles and 24 genotypes, 8 alleles and 27 genotypes, 7 alleles and 22 genotypes, 4 alleles and 10 genotypes, 6 alleles and 17 genotypes, 5 alleles and 13 genotypes were observed at D7S1808, D7S2250, D7S2251, D7S683, D7S656 and D7S528. The heterozygosities at the above 6 STR loci were 86%, 88%, 83%, 79%, 85% and 80%, respectively. Five alleles and 15 genotypes, 5 alleles and 15 genotypes, 8 alleles and 29 genotypes, 6 alleles an
