A total of 146 different haplotypes were observed and the haplotype diversity was 0.9887. The number of haplotypes seen once was 108 and the most common haplotype was observed in 12 males. A significant F_ST value was observed (F_ST = 0.012, P < 0.00001) when comparing the population of 15 locations in Greenland assigned to 7 groups. The significance could mainly be attributed to the subpopulation of males from Tasiilaq (East of Greenland). The R_ST value was not statistically significant (R_ST = 0.016, P = 0.15).     

Distribution of Y-chromosome STR defined haplotypes in Iberia

Seven Y-specific STR loci (DYS19, DYS389I, DY5389II, DYS390, DYS391, DYS392 and DYS393) were studied in five populations from the Iberian Peninsula: Andalusia, Valencia, Basque Country, Galicia and Northern Portugal. Haplotype and allele frequencies of these seven Y-chromosome STRs were estimated. Observed haplotype diversities are in a range between 0.96 (Basque Country) and 0.99 (Valencia and Andalusia). Significant population differentiation was registered between Basques and all the other Iberian populations and also between Valencia and Northern Portugal.

In this study, 12 Y-STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS437, DYS438 and DYS439) were genotyped in the three major ethnic populations in Singapore, namely the Chinese, Malay and Indian. Allele frequency distribution, locus diversity, haplotype diversity and discrimination capacity were estimated. Analysis of molecular variance between the three ethnic populations indicated that 87.71% of the haplotypic variation is found within population and 12.29% is between populations (Fixation Index FST=0.123, p=0.000). Population pairwise comparisons showed significant Phist values between all population pairs, with the lowest (RST=0.05) for Chinese-Malay and the highest (RST=0.19) for Chinese-Indian.     

Allele frequencies of 15 STR loci of Luoba ethnic group in Tibet (Southwestern China)

Allele frequency data for 15 short tandem repeat (STR) loci included in the AmpFlSTR Identifiler kit were obtained from a sample of 93 healthy unrelated individuals of Luoba population born in Tibet Autonomy Region of China (Southwestern China). In these samples, 141 alleles and 365 genotypes were observed for 15 STR loci. The distribution of these observed genotypes were not significantly different from the expected distribution according to Hardy-Weinberg equilibrium.
