🇵🇹🇵🇹🇵🇹 Portugal autosomal DNA analysis Request made by:-https://justpaste.it/mjnwn Notes from author:- .Average Portuguese being Iberian is combination of Celtic,Iberian,Imperial Roman and North African. .Average Portuguese sample with 53 samples score perfect north african percentage which doesn't contradict with research approximately .One Portuguese sample with name "Portugal3" lacks Imperial Rome dna. .Highest Celtic percentage was recorded 64.2% among these samples. .Sample with name "Portugal7" scores highest Iberian among Portuguese samples. ."Portugal2" sample score high Imperial_Rome dna among Portuguese samples. .Highest North African dna among Portuguese samples was detected in "Portugal3" ."However, North African ancestry only became widespread in Iberia in the past ~2000 years, associated with the Roman Empire or earlier Punic presence and the later period of Muslim rule" Source:-https://pmc.ncbi.nlm.nih.gov/articles/PMC6436108/ .Olalde et al. (2019) found evidence for 'sporadic contacts' between Iberia and North Africa in the Copper Age and Bronze Age. A male sample from central Iberia, dating from 2473–2030 cal BCE, was found to cluster with modern and ancient North Africans, characterised by ancestry from both Late Pleistocene North Africans and Early Neolithic Europeans. Another Bronze Age sample had 25% such North African ancestry  Comments of researchers:- 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). Substantially lower levels of North African admixture were further detected in Northern Italians (0.77%) and Tuscans (1%). https://academic.oup.com/mbe/article/37/4/1041/5670533 Bycroft et al. (2019) identified regionally varying fractions of Northwest African ancestry in modern Iberians, ranging from 0–12%. This ancestry was found to be from a source population similar to modern Northwest Africans. The admixture was dated to 860–1120 CE, associated with the Muslim conquest and subsequent Reconquista. The highest levels of Northwest African admixture were identified in western Iberia whilst the lowest levels were found in the Basque region and an area in the North East roughly corresponding to the 14th-century Crown of Aragon. They also found some evidence for a second admixture event in Portuguese and Southern Spanish groups involving a second North African population within which a small sub-Saharan African component was detected. This admixture event was dated to approximately 1300 CE https://pmc.ncbi.nlm.nih.gov/articles/PMC6358624/ Botigué et al. (2013) analysed genome-wide SNP data from over 2,000 modern individuals from Iberia. They estimated an average of 4% to 12% Northwest African admixture in modern Iberians (with low or zero levels in Basques), whereas populations in southeastern Europe had less than 2% of such admixture. Sub-Saharan African ancestry was detected at less than 1% in Europe, with the exception of the Canary Islands. https://pmc.ncbi.nlm.nih.gov/articles/PMC3718088/ Lazarids et al. (2014) detected 12.6 ± 2% North African ancestry and an average of 1.5 ± 0.2% sub-Saharan ancestry in the Spanish population https://pmc.ncbi.nlm.nih.gov/articles/instance/4170574/bin/NIHMS613260-supplement-supplement_1.pdf Research:-https://www.biorxiv.org/content/10.1101/2024.03.13.584607v2.full Calculator:-https://justpaste.it/jjhjw русский:-https://justpaste.it/jo8el Clear image:-https://justpaste.it/kq5ai @illyrianometer
