The European genetic structure today (based on 273,464 SNPs). Three levels of structure as revealed by PC analysis are shown: A) inter-continental; B) intra-continental; and C) inside a single country (Estonia), where median values of the PC1&2 are shown. D) European map illustrating the origin of sample and population size.
The research identified Roman ancestry in individuals from southern Germany, Italy, Poland, Slovakia, and southern Britain, with one person in southern Europe exhibiting 100 per cent Scandinavian ...
Hernandez et al. (2020) identified 11.17 ± 1.87% North African ancestry in southern Portuguese samples (from a population similar to modern northern Moroccans and Algerians), 9.28 ± 1.79% of such ancestry in western Andalusians, and an average of 1.41 ± 0.72% sub-Saharan ancestry in southern Iberians (using Yoruba as a proxy source ...
There is close genetic affinity among some Northwest European populations, [17] with some of these populations descending from Bell Beaker populations carrying steppe ancestry. [citation needed] For example, the Beaker people of the lower Rhine overturned 90% of Great Britain's gene pools, replacing the Basque-like neolithic populations present ...
The majority, around 70.1% fell into haplogroups and subclades of I, R1a and R1b which are specific to European populations. [1] The top four Y-DNA haplogroups among the sample of 1228 Russians are: [1] Haplogroup R1a (Y-DNA) – with an average of 46.7%; Haplogroup I (Y-DNA) – with an average of 17.6%; Haplogroup N (Y-DNA) with an average of ...
Living DNA uses SNP chips to provide reports on autosomal ancestry, Y, and mtDNA ancestry. [102] [103] Living DNA provides detailed reports on ancestry from the UK as well as detailed Y chromosome and mtDNA reports. [104] [105] [106] In 2019 it was estimated that large genealogical testing companies had about 26 million DNA profiles.
