Y-chromosome polymorphism data in Majorcan, Minorcan and Valencian populations (eastern Spain) Gema Jime´nez, Anto`nia Picornell*, Carmen Toma`s, Jose´ A. Castro, M. Miserico`rdia Ramon Departament de Biologia, Laboratori de Gene`tica, Universitat de les Illes Balears, Cra.

Abstract Frequency data of the six STRs: (1) DYS19; (2) DYS389I; (3) DYS389II; (4) DYS390; (5) DYS391 and (6) DYS393, and the DYS287 polymorphism (YAP) were determined in a sample of 117 unrelated males from three eastern Spanish populations: 53 from Majorca, 40 from Minorca and 24 from Valencia. # 2001 Elsevier Science Ireland Ltd. All rights reserved. Keywords: Y-chromosome; Short tandem repeats; YAP; Population data; Eastern Spain

Population: Autochthonous unrelated males from Valencia and the islands of Majorca and Minorca. Previous Y-chromosome studies in Valencian population can be found in the literature [1,2]. Extraction: Standard phenol/chloroform DNA extraction [3]. PCR: The five Y-chromosome STRs (1) DYS19; (2) DYS389I; (3) DYS389II; (4) DYS390 and (5) DYS391 were co-amplified using approximately 15 ng of genomic DNA in a total reaction volume of 25 ml following the method of Gusma˜o et al. [4], with modifications. PCR amplification of DYS393 and DYS287 was achieved in singleplex under standard conditions with the primer sequences obtained from the literature. All loci were amplified in a GeneAmp PCR System 2400 (PE Applied Biosystems). Typing: ABI 310 for the pentaplex, PAGE (6%) in nondenaturing conditions for the DYS393 system [5] and 2% agarose gels for DYS287. In all cases, reference sequenced ladders (PE Applied Biosystems) or our own allele ladders were used.

Results: See Tables 1–4. Analysis of data: ARLEQUIN package [6]. Access to the data: [email protected]. Other remarks: Comparisons between all of the three populations studied showed no significant differences. FST values between these populations and other Spanish (Andalusia, Catalonia, Galicia, Valencia and Basques) and Portuguese populations only showed significant differences between the Majorcan and Andalusian and Portuguese. No evidence of significant allele association was observed in the pairwise comparisons between loci, except in DYS19 versus DYS287.

For DYS389II, the number of repeats was obtained by subtracting the length of the corresponding DYS389I allele [7].
