The foremost pioneer of the study of population genetics was Luigi Luca Cavalli-Sforza.Cavalli-Sforza used classical genetic markers to analyse DNA by proxy. This method studies differences in the frequencies of particular allelic traits, namely polymorphisms from proteins found within human blood (such as the ABO blood groups, Rhesus blood antigens, HLA loci, immunoglobulins, G-6-P-D ...
The Portuguese people (Portuguese: Portugueses – masculine – or Portuguesas) are a Romance-speaking ethnic group and nation indigenous to Portugal, a country that occupies the west side of the Iberian Peninsula in south-west Europe, who share culture, ancestry and language. [87] [88] [89]
This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable. The tests have been promoted by amateur groups, such as surname study groups or regional genealogical groups, as well as research projects such as the Genographic Project. As of 2019, about 30 million people had been tested. As ...
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output.

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 ...
Farther east, the issue is less contentious. Haplogroup N carriers account for a significant part of all non-Slavic ethnic groups in northern Russia, including 37% of Karelians, 35% of Komi people (65% according to another study [56]), 67% of Mari people, as many as 98% of Nenets people, 94% of Nganasans, and 86% to 94% of Yakuts.

Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), [1] and European contact, after about 500 years ago.
