Part A: Genetic Profile: Your unique genetic profile includes the values for 26 genetic markers distributed throughout your autosomal chromosomes. For each marker (also known as a “locus”) you have two values (“alleles”): one inherited from your father and the other inherited from your mother, for a total of 52 dimensions used to perform your DNA Tribes’ ancestry testing. More specifically, your unique combination of alleles is used to compute high resolution Native Population, Global Population and World Region matches.
Comments for this sample individual: At each locus, this individual inherited one allele value from their mother and one from their father. Each allele value is a number representing repeats of a particular genetic sequence. For instance, at locus D21S11, this individual has inherited one allele of length 29 (29 repeats) and one allele of length 30 (30 repeats). Because these alleles are passed down independently on separate chromosomes, it would be necessary to test a parent to determine which allele was passed down by which parent. This DNA profile serves as a genetic fingerprint for this person, and this collection of allele values is used to compute this person’s connections to individual populations and World Regions in the DNA Tribes’ reference database.
Part B: High Resolution Native Population Match: DNA Tribes identifies your Top 20 matches in our reference database of more than 900 native populations that have experienced minimal movement and admixture in the last 500 years. Individual population matches do not necessary indicate recent social or cultural affiliation with a particular ethnicity. Instead, the geographical distribution of your Native Population Match results indicates your most likely deep ancestral origins.
DNA matches do not necessarily suggest a recent family ancestor from each country listed and can express the genetic traces of more ancient relationships between populations through shared origins, migrations, and long term trade contacts in each part of the world. For people with mixed ancestry, DNA matches can also identify populations where similar mixing has taken place (such as native populations located near historical trade and migration routes between continents).
Comments for this sample individual: The Top 20 Native population matches based on MLI scores for this individual are with European populations. The listed individual MLI scores do not indicate the percentage of individual’s genetic material attributable to individual populations. Instead, these MLI scores assess the relative likelihood of this person’s genetic make-up occurring in a particular population:
For example, the strongest match for this person is with a population from the United Kingdom, where this individual’s DNA profile is 5,957,304 times as likely to occur as in the world as a whole. A TribeScore of (0.97) indicates that this person’s MLI score is higher than scores for 97% of individuals from this population; thus, this individual’s genetic make-up fits the data from the United Kingdom sample very well.
However, similar DNA profile to our example European person can be found in other populations of Europe: the MLI score for a sample from Belgium is 4,289,015, indicating that this example DNA profile is 5,957,304 / 4,289,015 = 1.4 times more likely to occur in the United Kingdom population than in the Belgian population (based on the ratio of the MLI scores for these two populations). In addition, the TribeScore of (0.96) for Belgium indicates that 96% of individuals from this population would have lower MLI scores than the sample individual; hence, this individual’s MLI score is quite high for this population.
For this example individual, the United Kingdom could be a likely native population of origin among the Native populations included in the DNA Tribes reference database; however, other populations with very high matches (e.g., Belgium and Wales) cannot be excluded. In addition to a large number of Northwest European populations in their Top 20, this individual also has strong matches with populations in the Iberian peninsula (e.g., Portugal and Spain). This could imply that this individual has ancestry from both Northwest Europe and the Iberian peninsula; however, it could also reflect gene flow between the British Isles and the Iberian peninsula from the antiquity through the modern age.
Note: Some countries/regions appear multiple times in the Top 20 (e.g., multiple matches for the United Kingdom and Belgium are listed). This is due to multiple population samples available for each country/region and each MLI score represents an independent comparison of an individual’s DNA to a particular sample.
Part C: High Resolution Global Population Match: The Global matches for this example individual are exactly the same as their Native matches in Part B. This indicates that this individual’s genetic make-up is most common in the relatively non-mixed native European populations and less common in the mixed European Diaspora populations (e.g., Europeans in the United States or Canada).
Comments for this sample individual: The Global matches for this example individual are exactly the same as their Native matches in Part B. This indicates that this individual’s genetic make-up is most common in the relatively non-mixed native European populations and less common in the mixed European Diaspora populations (e.g., Europeans in the United States or Canada).
Part D: High Resolution World Region Match World Region matches measure your genetic connections to major genetic World Regions identified by DNA Tribes using proprietary statistical algorithms. Each World Region is comprised of multiple populations that are geographically adjacent and genetically similar.
Comments for this sample individual: World Region results provide the most robust assessment of the person’s genetic connections to the world. They can often clarify and confirm individual Native and Global population match results. For instance, this sample individual’s DNA profile is most common in the Northwest European World Region (the highest MLI score) and slightly less common in the Iberian World Region (the second highest MLI score). This is consistent with the distribution of this person’s Native and Global population matches in Parts B and C, which are strongest for the British Isles populations and slightly weaker for Iberian populations. More precisely, this individual’s DNA profile is most frequent in the Northwest European World Region, where it is 1,396,637 times more likely to occur than in the world as a whole. This individual’s second highest match is with the Iberian World Region (MLI of 1,040,945). Hence, this individual’s genetic make-up is 1,396, 637 /1,040,945 = 1.3 times more likely to occur in the populations of Northwest Europe than in the populations of the Iberian peninsula.
In addition, for this individual substantial MLI scores include other European World Regions (e.g., Baltic-Slavic and Aegean). These secondary affiliations indicate that this example European profile can also be found with lower likelihood in other World Regions.
Summary Comments:DNA Tribes ancestry test results for this person provide a detailed and comprehensive picture of their European ancestry identifying their closest genetic relatives among European populations and World Regions.
