With the help of DNA examination, specialists receive answers to several very important questions related to the personal data of the individual. Deoxyribonucleic acid is studied when it is necessary to find out the origin of an individual, to identify family and genealogical relationships, to confirm/deny the involvement of a person in various actions or events.
Such a study provides the most accurate answers to the following questions:
Ethnic origin of man
Using high-tech equipment, specialists determine which of the 4 ethnic groups (European, African, East Asian or Southeast) DNA samples of a particular individual belong to. The test result will show the percentage of each group in the unit of the studied material as a percentage. Quite often, trying to establish their ethnicity, people think that they will be helped to determine the nationality of distant ancestors, to determine on which lands their genus originates. However, the analysis of ethnic origin does not give an answer – what nationality were the distant ancestors of man.
Genealogy of the genus
If a person needs to restore family ties for several years or a longer time, to collect the most complete information about all possible relatives, as well as confirm or deny kinship, genealogy analysis will help.
Family ties
The most common test is to establish paternity (to do this, take the Y-chromosome, the so-called “paternal”, transmitted along the male line in the genus).
Racial affiliation
Especially a lot of confusion arises when conducting DNA analysis for belonging to a particular race. Race and nationality are not identical definitions, for example – if the results indicate that the individual belongs to the Caucasian race, it is absurd to conclude that he has a Caucasian ethnicity.
So how can you determine the origin of the DNA test?
This will help genogeography – a science at the intersection of genetics, geography and history, which allows you to track the migration of peoples. The fact is that once every 10-15 thousand years, mutations take root in DNA that allow you to separate one genetic branch from another. Having studied what mutations are characteristic of residents of various points on the map of the Earth, scientists were able to compile maps of the movements of all haplogroups.
Now it’s enough to find out which one you belong to to see which route your great-great ones were moving. Moreover, if the DNA of men contains information about the origin of both parents, then only data about mother’s roots are available to women. Information about the ancestors of the papal line is contained in the Y-chromosome, which is absent in women.
Good luck in finding.
