Haplotype Frequencies of Four Y-chromosome STR Loci in Chinese Population.

Investigates the haplotype frequencies of Y-chromosome STR loci in Chinese population. Development of a multiplex amplified for these Y-STR markers; Sufficiency of the sample size for the research purpose; Sensitivity and reliability of using non-denaturing polyacrylamide gel electrophoresis and visualized silver staining in the analysis of the PCR products.
