Y-chromosome STR haplotypes in Danes

Forensic and population genetic analyses of Danes, Greenlanders and Somalis typed with the Yfiler ® Plus PCR amplification kit

“…With the exception of one locus in one individual, there was complete concordance between the genotypes generated with the various Y-STR kits [10][11][12][13]15]. In the DYF387S1 locus, one Danish individual was typed as 35.3; 38 with Yfiler 1 Plus and as 35.2; 38 with the multiplex of Ballantyne et al [13].…”

“…The electropherograms were analysed using GeneMapper 1 IDX v. 1.4 (Thermo Fisher Scientific, Waltham, MA, USA) with the default settings except that the peak amplitude thresholds were set to 75 RFU for the blue and green, 125 RFU for the yellow, 175 RFU for the red and purple and 50 RFU for the orange colurs. All the results were compared with previously published data on the PPY 1 12 [10][11][12], Yfiler 1 [13,14], RM-Y-STRs [13], and PPY 1 23 [15] using an in-house written script in the statistical software program R v. 2.15.3 [16]. Additionally, 28 of the male Somalis were typed with Yfiler 1 .…”

“…The Yfiler 1 Plus results from this study were combined with previously published Y-STR data for Danes, Greenlanders and Somalis [10][11][12][13]15] (Table S2). Forensic parameters were calculated based on the haplotypes for different sets of Y-STR loci (Table S5).…”

Genetic sub-structure in western Mediterranean populations revealed by 12 Y-chromosome STR loci

“…[23], Pyrenees [21], Barcelona [33], Portugal [26], Italy [29], the Balkans [5], Tunisia [9], Denmark [18], Majorca, Valencia, Ibiza, Catanzaro, Cosenza, Reggio Calabria and Sicily (this study)) significantly different sub-sets: one with the Spanish populations (Valencia, Ibiza and Majorca) and another with the Calabrian samples (Catanzaro, Cosenza and Reggio Calabria). Sicily was closer to the Italian than to the Spanish populations, although presented significant differences with Reggio Calabria (P<0.005).…”

Identifying the most likely contributors to a Y-STR mixture using the discrete Laplace method

“…All haplotypes consisted of loci with only one allele. The datasets used were Danes [4,5] (n = 181, 21 loci using the PPY23 kit excluding DYS385a/b), Somalis [6] (n = 201, 10 loci using the PowerPlex Y kit excluding DYS385a/b) and a compilation of 14 German populations [7] (n = 3443, 7 loci excluding DYS385a/b, the used kits were stated). The Danish dataset was truncated to 15 loci (corresponding to Yfiler (Thermo Fisher)) and 10 loci (corresponding to PowerPlex Y (Promega)) in order to observe the effect of varying numbers of loci.…”
