Y-chromosome mismatch distributions in Europe
Pereira, L; Dupanloup, I; Rosser, ZH; Jobling, MA; Barbujani, GAncient demographic events can be inferred from the distribution of pairwise sequence differences (or mismatches) among individuals. We analyzed a database of 3,677 Y chromosomes typed for 11 biallelic markers in 48 human populations from Europe and the Mediterranean area. Contrary to what is observed in the analysis of mitochondrial polymorphisms, Tajima's test was insignificant for most Y-chromosome samples, ...
Y-chromosomal diversity in Europe is clinal and influenced primarily by geograp...
Rosser, ZH; Zerjal, T; Hurles, ME; Adojaan, MA; Alavantic, D; Amorim, A; Amos, W; Armenteros, M; Arroyo, E; Barbujani, G; Beckman, L; Bertranpetit, JClinal patterns of autosomal genetic diversity within Europe have been interpreted in previous studies in terms of a Neolithic demic diffusion model for the spread of agriculture; in contrast, studies using mtDNA have traced many founding lineages to the Paleolithic and have not shown strongly clinal variation. We have used 11 human Y-chromosomal biallelic polymorphisms, defining 10 haplogroups, to analyze a sa...
