In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by Ernst Mayr in 1942, [ 1 ] using existing theoretical work by those such as Sewall Wright . [ 2 ]
The founder population could be the common ancestry of Arabs or the forced localizations caused by artificial countries inside the larger group of ancestry, hence causing Arab specific founder effect mutation disease found only in all Arabic countries, and Arabic country specific mutation diseases caused by increasing Homozygosity (the ...
Because of a founder effect, the ancestors of present-day Ashkenazi Jews may have kept the low-frequency G2019S mutation through the different diasporas, whereas Near Eastern daughter populations lost the mutation. The mutation might then have been "reintroduced by recurrent gene flow from Ashkenazi populations to other Jewish, European, and ...
R-M167 is a subclade of R-DF27 defined by the presence of the marker M167. The first author to test for this marker (long before current haplogroup nomenclature existed) was Hurles in 1999, who tested 1158 men in various populations. [63] He found it relatively common among Basques (13/117: 11%) and Catalans (7/32: 22%).
After taking two DNA tests, one from AncestryDNA and one from 23andMe, I finally got my answers. And the experience has provided me with some important pieces of advice for anyone who wants to ...

The only significant differences among the populations were in linguistics and genetics. "The high allelic frequency levels at or near fixation is the result of genetic drift, bottle neck events and/or the founder effect.” [2] The founder effect was defined for the low heterozygosity amongst the Quiche and Cakchiquel. The Yucatán Mayans ...
