Objective:
The study was conducted to reveal the distribution of genetic polymorphism of four Y chromosome specific short tandem repeat (Y-specific STR) loci in Li ethnic groups in Hainan Island, China.
Methods:
Four tetranucleotide STR loci were simultaneously amplified with fluorescently labeled primers, and genotypes were determined with an automated DNA sequencer.
Results:
Among 230 unrelated males, the alleles at the four Y-specific STR loci were composed of some complex repeat structure. 4,5,4,5 alleles were observed in loci DYS3891, DYS390, DYS391, DYS393 respectively. A set of human allele ladders for the typing of the four Y-specific STRs was obtained in Li ethnic population. Gene diversity index (D) and haplotype diversity data were estimated for the four Y-STRs.
Conclusion:
The preliminary study indicates a reference population for detecting male migration events and should be useful in population genetics and forensic applications.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
