The timing of pigmentation lightening in EuropeansSandra Beleza
IPATIMUP, Instituto de Patologia e Imunologia Molecular da Universidade do Porto, Porto, Portugal
Mol Biol Evol 30:24-35. 2013..We suggest that these patterns were influenced by recent increases in size of human populations, which favored the accumulation of advantageous variants at different loci...
The genetic legacy of western Bantu migrationsSandra Beleza
Instituto de Patologia e Imunologia, Universidade do Porto, Rua Dr Roberto Frias, S N, 4200 465 Porto, Portugal
Hum Genet 117:366-75. 2005..The data also indicate that the western stream of the Bantu expansion was a more gradual process than the eastern counterpart, which likely involved multiple short dispersals...- Extending STR markers in Y chromosome haplotypesS Beleza
IPATIMUP, Instituto de Patologia e Imunologia Molecular da Universidade do Porto, Rua Dr Roberto Frias, S N, 4200 Porto, Portugal
Int J Legal Med 117:27-33. 2003..For instance, in our sample the addition of the DYS437, DYS438 and GATA A7.2 to a 13-locus set increased haplotype diversity only by 0.0001... - Micro-phylogeographic and demographic history of Portuguese male lineagesSandra Beleza
Instituto de Patologia e Imunologia da Universidade do Porto IPATIMUP, Rua Dr Roberto Frias s n, 4200 465 Porto, Portugal
Ann Hum Genet 70:181-94. 2006..The finding of a broadly homogeneous background for the Portuguese population has vast repercussions in forensic, epidemiological and association studies... - 17 STR data (AmpF/STR Identifiler and Powerplex 16 System) from Cabinda (Angola)S Beleza
Department of Population Genetics, Instituto de Patologia e Imunologia Molecular da Universidade do Porto, R Dr Roberto Frias s n, Porto 4200 465, Portugal
Forensic Sci Int 141:193-6. 2004..Comparative analyses between our population data and other African databases, namely Promega's African-Americans, AB Applied Biosystems African-Americans and five other population samples gathered from the literature are also presented... - Grouping of Y-STR haplotypes discloses European geographic clinesLeonor Gusmao
IPATIMUP, Instituto de Patologia e Imunologia, Molecular da Universidade do Porto, 4200 465 Porto, Portugal
Forensic Sci Int 134:172-9. 2003.... - Bimodal allele frequency distribution at Y-STR loci DYS392 and DYS438: no evidence for a deviation from the stepwise mutation modelLeonor Gusmao
IPATIMUP, Instituto de Patologia e Imunologia Molecular da Universidade do Porto, Rua Dr Roberto Frias s n, 4200 465, Porto, Portugal
Int J Legal Med 117:287-90. 2003..The loci do therefore not appear to warrant any special attention when applied in population genetic or forensic studies... - Forensic evaluation and population data on the new Y-STRs DYS434, DYS437, DYS438, DYS439 and GATA A10L Gusmao
IPATIMUP, Instituto de Patologia e Imunologia Molecular da Universidade do Porto Rua Dr Roberto Frias, S N, 4200 465 Porto, Portugal
Int J Legal Med 116:139-47. 2002..68% increase in haplotype diversity was obtained and the number of different haplotypes rose from 157 to 196. When DYS434 was not considered the haplotype diversity was not affected... - On the edge of Bantu expansions: mtDNA, Y chromosome and lactase persistence genetic variation in southwestern AngolaMargarida Coelho
IPATIMUP, Instituto de Patologia e Imunologia Molecular da Universidade do Porto, R Dr Roberto Frias s n, 4200 465 Porto, Portugal

Department of Genetics, Stanford University School of Medicine, Stanford, California, United States of America Instituto de Patologia e Imunologia Molecular da Universidade do Porto IPATIMUP, Porto, Portugal
PLoS Genet 9:e1003372. 2013....- The admixture structure and genetic variation of the archipelago of Cape Verde and its implications for admixture mapping studiesSandra Beleza
IPATIMUP, Instituto de Patologia e Imunologia Molecular da Universidade do Porto, Porto, Portugal
PLoS ONE 7:e51103. 2012.... - Results of the GEP-ISFG collaborative study on two Y-STRs tetraplexes: GEPY I (DYS461, GATA C4, DYS437 and DYS438) and GEPY II (DYS460, GATA A10, GATA H4 and DYS439)Paula Sanchez-Diz
Institute of Legal Medicine, University of Santiago de Compostela, Compostela, Spain
Forensic Sci Int 135:158-62. 2003..However, since GATA C4 repeat presents a complex structure, with alleles differing in sequence structure, efficient denaturing conditions should be followed in order to avoid typing errors due to sizing problems... - Population data of Galicia (NW Spain) on the new Y-STRs DYS437, DYS438, DYS439, GATA A10, GATA A7.1, GATA A7.2, GATA C4 and GATA H4Beatriz Quintans

Forensic Sci Int 131:220-4. 2003..1, GATA A7.2, GATA C4 and GATA H4, were determined from a sample of 212 unrelated male individuals from Galicia (NW of Spain)... - The genetic architecture of normal variation in human pigmentation: an evolutionary perspective and modelBrian McEvoy
Smurfit Institute of Genetics, Trinity College Dublin, Dublin 2, Ireland
Hum Mol Genet 15:R176-81. 2006..However, these should be viewed as complements, rather than replacements of, functional studies including linkage and association analyses, which can directly refine our understanding of the trait...
