The variation was perhaps initially low or structured by geography but was subsequently accentuated by religion-driven migration into specific communities within Lebanon. Two of the three major migrations have left a detectable impact, and conversely, the main features of the differentiation within Lebanon can be accounted for by these events. It is likely that earlier migratory events have also contributed to the genetic diversity in present-day Lebanese populations, but because these migrations would have occurred before the present religious affiliations and communities were created, they are expected to have shaped the genetic makeup of the country as a whole rather than specific religious subpopulations.\nGenetic structuring by religion has been rarely reported in human populations: it was not detectable, for example, among Muslim and Hindu paternal45 or maternal46 lineages in India. A Y-chromosomal lineage that is rare in India but common in western Asia was found at unusually high frequency in an Indian Shiya Muslim sample47, and structuring by religion has been seen among Jewish maternal (although not paternal) lineages48. Such structure might only arise when several unusual criteria are met: migrations based on religion must take place between areas with different representative Y-chromosomal types, and they must establish genetically differentiated communities that remain stable over long time periods. In Lebanon, these conditions appear to have been met for over 1,300 years.","divisions":[{"label":"title","span":{"begin":0,"end":10}},{"label":"p","span":{"begin":11,"end":877}}],"tracks":[{"project":"2_test","denotations":[{"id":"18374297-16951948-2052374","span":{"begin":1024,"end":1026},"obj":"16951948"},{"id":"18374297-17427927-2052375","span":{"begin":1038,"end":1040},"obj":"17427927"},{"id":"18374297-11992249-2052376","span":{"begin":1303,"end":1305},"obj":"11992249"}],"attributes":[{"subj":"18374297-16951948-2052374","pred":"source","obj":"2_test"},{"subj":"18374297-17427927-2052375","pred":"source","obj":"2_test"},{"subj":"18374297-11992249-2052376","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#ec9893","default":true}]}]}}
