Haplotype frequencies of eight Y-chromosome STR loci in Barcelona (North-East Spain)

Abstract

Haplotype frequencies for eight Y-chromosomal short tandem repeat (STR) loci were determined in paragraph signa population sample from Barcelona (NE Spain). After PCR amplification and denaturing PAGE electrophoresis, DYS19, DYS388, DYS389 I/II, DYS390, DYS391, DYS392 and DYS393 loci were typed. Complete eight paragraph signY-chromosomal STRs haplotypes could be formed for 223 subjects, among which 137 different haplotypes were observed. The most common haplotype was shared by 13% of the sample, while 108 haplotypes were unique. The discrimination capacity was 61.5% and the gene diversity was 0.978. From the forensic point of view the combined polymorphisms provide a high diagnostic efficiency.

Seventeen Y-chromosomal short tandem repeat haplotypes in seven groups of population living in Taiwan

“…Briefly, gene or haplotype diversity was estimated according to the formula presented by Nei [21]. The discrimination capacity was assessed as the percentage proportion of individual-specific haplotypes [22]. The genetic relationship between different populations was calculated following the description by Excoffier et al [23,24].…”

Haplotype analysis with 14 Y-STR loci using 2 multiplex amplification and typing systems in 2 regional populations in Japan

“…The gene or haplotype diversity (h) was calculated as h = n x 2 i / (n − 1) , where n is the number of individuals and x i is the frequency of each allele or haplotype (Nei 1987). The discrimination capacity was calculated as the percentage proportion of unique haplotypes (Gené et al 1999). …”
