However, its multi-layered history of migration pathways and cultural exchanges, has made the reconstruction of its genetic history and population structure extremely controversial and widely debated. To address this debate, we surveyed the genetic variability of 326 accurately selected individuals from 8 different provinces of Sicily and Southern Italy, through a comprehensive evaluation of both Y-chromosome and mtDNA genomes. The main goal was to investigate the structuring of maternal and paternal genetic pools within Sicily and Southern Italy, and to examine their degrees of interaction with other Mediterranean populations. Our findings show high levels of within-population variability, coupled with the lack of significant genetic sub-structures both within Sicily, as well as between Sicily and Southern Italy. When Sicilian and Southern Italian populations were contextualized within the Euro-Mediterranean genetic space, we observed different historical dynamics for maternal and paternal inheritances. Y-chromosome results highlight a significant genetic differentiation between the North-Western and South-Eastern part of the Mediterranean, the Italian Peninsula occupying an intermediate position therein. In particular, Sicily and Southern Italy reveal a shared paternal genetic background with the Balkan Peninsula and the time estimates of main Y-chromosome lineages signal paternal genetic traces of Neolithic and post-Neolithic migration events. On the contrary, despite showing some correspondence with its paternal counterpart, mtDNA reveals a substantially homogeneous genetic landscape, which may reflect older population events or different demographic dynamics between males and females. Overall, both uniparental genetic structures and TMRCA estimates confirm the role of Sicily and Southern Italy as an ancient Mediterranean melting pot for genes and cultures.</p>", "link"=>"http://www.mendeley.com/research/ancient-mediterranean-melting-pot-investigating-uniparental-genetic-structure-population-history-sic", "reader_count"=>27, "reader_count_by_academic_status"=>{"Unspecified"=>1, "Professor > Associate Professor"=>1, "Librarian"=>1, "Researcher"=>3, "Student > Ph.

In particular, Sicily and Southern Italy reveal a shared paternal genetic background with the Balkan Peninsula and the time estimates of main Y-chromosome lineages signal paternal genetic traces of Neolithic and post-Neolithic migration events. On the contrary, despite showing some correspondence with its paternal counterpart, mtDNA reveals a substantially homogeneous genetic landscape, which may reflect older population events or different demographic dynamics between males and females. Overall, both uniparental genetic structures and TMRCA estimates confirm the role of Sicily and Southern Italy as an ancient Mediterranean melting pot for genes and cultures.</p></div>", "links"=>[], "tags"=>["Evolutionary biology", "Evolutionary genetics", "population genetics", "genetics", "genomics", "Human genetics", "Molecular genetics", "Physical anthropology", "Population biology", "geography", "Human geography", "anthropology", "mediterranean", "melting", "investigating", "uniparental", "sicily"], "article_id"=>1010105, "categories"=>["Biological Sciences", "Science Policy"], "users"=>["Stefania Sarno", "Alessio Boattini", "Marilisa Carta", "Gianmarco Ferri", "Milena Alù", "Daniele Yang Yao", "Graziella Ciani", "Davide Pettener", "Donata Luiselli"], "doi"=>["https://dx.doi.org/10.1371/journal.pone.0096074.s001", "https://dx.doi.org/10.1371/journal.pone.0096074.s002", "https://dx.doi.org/10.1371/journal.pone.0096074.s003", "https://dx.doi.org/10.1371/journal.pone.0096074.s004", "https://dx.doi.org/10.1371/journal.pone.0096074.s005", "https://dx.doi.org/10.1371/journal.pone.0096074.s006", "https://dx.doi.org/10.1371/journal.pone.0096074.s007", "https://dx.doi.org/10.1371/journal.pone.0096074.s008", "https://dx.doi.org/10.1371/journal.pone.0096074.s009"], "stats"=>{"downloads"=>36, "page_views"=>21, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/_An_Ancient_Mediterranean_Melting_Pot_Investigating_the_Uniparental_Genetic_Structure_and_Population_History_of_Sicily_and_Southern_Italy_/1010105", "title"=>"An Ancient Mediterranean Melting Pot: Investigating the Uniparental Genetic Structure and Population History of Sicily and Southern Italy", "pos_in_sequence"=>0, "defined_type"=>4, "published_date"=>"2014-04-30 03:08:03"}
