Abstract Haplotype data were obtained from a sample of 173 unrelated male individuals from Cartagena (Colombia), for 16 Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635, GATA H4 and GATA A10). No shared haplotypes were observed, demonstrating the usefulness and informative power of these Y-STRs in male lineage identification in Cartagena. Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of Iberian origin. # 2006 Elsevier Ireland Ltd.

Population: Blood samples were obtained from 173 unrelated healthy male donors who were born in Cartagena, Bolı´var (Colombia, Fig. 1). DNA extraction: Salting-out [1]. PCR: DNA Amplification and detection of the amplicons were performed according to Builes et al. [2,3]. Alleles were typed by comparison with in-house constructed allelic ladders and the nomenclature follows and ISFG recommendations on Y chromosome STR analysis [4]. Quality control: Proficiency testing has been carried out for the proficiency testing of the GEP-ISFG working group [5] and the Y-STR haplotyping quality assurance exercise 2001 (http:// www.yhrd.org) [6]. Analysis of data: Haplotype frequencies were estimated by gene counting. Haplotype diversities were calculated according

to Nei [7] using the Arlequin software, version 2.000 [8]. Analysis of molecular variance (AMOVA) results were summarized in the form of sum of squared size differences Rst values and assessed for statistical significance using a Monte Carlo test as implemented in the referred software. UPGMA tree was built from the distance matrix (Rst) using the option neighbour and drawtree in the PHYLIP software package [9]. The tree was visualized with the Treeview software [10]. In population comparisons, DYS385 was not considered and the number of repeats in DYS389I was subtracted from DYS389II. Results: Table 1 shows the haplotype distribution in a sample of unrelated males from Cartagena for the 17 Y-chromosome STR loci, DYS19, DYS385, DYS389I and II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635, GATA H4 and GATA A10. No shared haplotypes were obtained between the 173 individuals studied. The sample yielded an overall haplotype diversity of 1.000 0.0006, demonstrating the usefulness and informative power of these Y-STRs in male lineage identification in

Cartagena, Colombia. Considering the ‘minimal haplotype’ included in the YHRD (Y-STR haplotype reference database; http://www.yhrd.org) [6], the most frequent haplotype observed in Europe (2.72%) and in Latin American population sample (varying from 1.25% in Argentina to 4.47% in Sa˜o Paulo) matches the most frequent haplotype in Cartagena (8.67%).

population of Cartagena is an admixture from Caucasians, African and in a less extent, Native American ancestries. Previously, we have evaluated the distribution of some alleles of the HLA complex in this population and found mainly alleles from both Caucasian and African populations [11]. Also, we have compared the distribution of some autosomal STRs between Cartagena and other Colombian and African populations and significant differences were found, except with two Colombian Caribbean Coast subregions [12]. The present haplotype data were compared with the previously published data available for the same set of Y-STR loci in samples from North Portugal [13], Spain [14], Rio de Janeiro [15], Cantabria [16], Mozambique [17] and Equatorial Guinea [18]. Pairwise analysis showed no significant differences (P > 0.05) in the comparison of Cartagena and Rio de Janeiro (Rst = 0.00784). With other Iberian origin samples from northern Portugal, Spain and Cantabria, although significant, low Rst values were obtained (0.013, 0.012 and 0.024, respectively). In the comparison with the remaining populations, highly significant distances were observed (P = 0.000). Considering the ‘minimal haplotype’ loci included in the YHRD [6], data from Cartagena were compared with those previously published Antioquia, Colombia [19], CaucasianMestizo, East-central Andean, Colombia [20], Afro-Colombian, Choco´, Colombia [20], Co´rdoba, Argentina [21], northern Portugal [13], Basque Country, Spain [22], Spain [14], Peru´ [23], Buenos Aires [24], Rio de Janeiro [15], Macau [25] and Equatorial Guinea [18]. The lowest, non-significant (P > 0.05), pairwise differences between the Cartagena and other populations were obtained in the comparison with Rio de Janeiro (Rst = 0.000) and Co´rdoba (Rst = 0.006) samples. With the samples from northern Portugal, Spain and Antioquia, although significant, low Rst values were obtained (0.019; 0.021 and 0.007, respectively). In the comparison with the remaining

populations, highly significant distances were observed (P = 0.000). Fig. 2 shows neighbour joining trees built from the Rst distance matrices between the seven (16 Y-STR haplotypes) and 13 (‘minimal haplotype’ loci) populations, respectively, where Cartagena sample clusters with European origin samples and stands far apart of the non-Caucasian samples: a Chinese sample from Macao (Rst = 0.134), two African samples from Mozambique (Rst = 0.343) and Equatorial Guinea (Rst = 0.306), a African origin sample from Choco´ (Rst = 0.162) and Native Americans from Peru´ (Rst = 0.212). These findings suggest a high proportion of male contribution of European origin in the population of Cartagena. Although a high degree of African genetic influence is present in Cartagena population [11], the present work results suggest that Cartagena presents a much higher proportion of European male lineages than those from African or Amerindian origin. This is in accordance with the sex-biased contribution of socially and economically asymmetric gene pools [26]. Nevertheless, the assignment of male lineages to each continent could only be evaluated by SNP analysis. Moreover, since data are only available for two African populations, we cannot discard the hypothesis that lower genetic distances could be obtained between Cartagena and other uncharacterized African populations. In summary, because of the significant genetic distances detected between Cartagena and other populations from Colombia, as well as those from Iberia and Africa, a specific Y STR haplotype database should be used in paternity and forensic cases in Cartagena. This paper follows the guidelines for publication of population data requested by the journal [27].
