Abstract:
Objective To study the genetic polymorphisms of 11 Y chromosome specific STR loci in Guangzhou Han population. Method The DNA extracted from blood samples of unrelated individuals in Han population living in Guangzhou were amplified by PCR. The PCR products were analyzed by using PAGE. Results 3-5 alleles were detected in 11 Y - STR loci respectively in Han population in Guangzhou. The minimum GD value was 0.3037 (DYS434), while the maximum GD value was 0.8455 (DYS390) . Conclusion The 11 Y - specific STR loci are highly polymorphic and are suitable for personal identification and paternity testing.
