Research on DNA for ethnic origin is gaining widespread popularity in modern society. This test allows you to establish family ties within 6 generations. Mankind has received a unique opportunity to find out information about establishing belonging to a particular ethnic group. The study also allows you to identify a person’s predisposition to certain diseases. This topic is relevant for people who are interested in the origin of a kind and want to know more about their ancestors.
Analysis Capabilities
The existence of kinship between people is identified by matching DNA with another person. This is due to the fact that deoxyribonucleic acid contains complete information about several generations of people. Ethnicity DNA test distinguishes some genetic branches from others.
Deoxyribonucleic acid is a kind of biological "passport" of a person. Therefore, conducting DNA research allows you to obtain information about ethnicity, analyze the origin of a person, and also identify a predisposition to genetic diseases. The information obtained will help to adjust nutrition, lifestyle, and also prevent the development of various pathologies. Carrying out a DNA test is of great practical importance in the modern world.
Types of analysis
DNA studies are classified as state-of-the-art analytical tests. Everyone can find relatives and find out the origin of their ancestors. Therefore, DNA analysis is a storehouse of the whole history of human evolution. Three types of genealogical DNA analysis can be distinguished:
- autosomal;
- mitochondrial;
- test Y (done for men, determines the direct paternal line).
Autosomal analysis is carried out on all branches of the family tree. Mitochondrial involves maternal studies. Test Y is carried out in relation to men, because it allows you to determine the paternal line. It is important to know that genealogy testing does not provide data on hereditary diseases and various disorders.
Why do you need analysis?
A DNA test for ethnicity allows you to refute or confirm the involvement of a person in the commission of certain actions or events. A study of this type gives an accurate answer about the ethnic origin of a person, the genealogy of the genus, race and family ties. Genealogy analysis will help to quickly collect complete information about possible relatives.
Materials for examination
Any genetic material will do for an ethnic DNA test. As a rule, they take a scraping of buccal epithelium or an oral smear. Some laboratories analyze discharge from various parts of the body. DNA can be isolated from blood, hair, bone tissue, earwax, etc. In addition, for the DNA test for ethnicity, you can use any items or personal items that have left over the remains of life.
As objects for testing, handkerchiefs, toothbrushes, nipples, razor blades, etc. are suitable. A standard DNA sample is a smear on the inside of the cheek. In the event that there is no opportunity to conduct analysis "by saliva," you can use non-standard samples. For example, dried blood, nails, body fluids, hair, etc. It is easier for men to conduct a study, since they will need to donate only their own genetic material. The situation is more complicated for women, since in addition to their biological material, it will be necessary to provide material from the father.
Where to get an ethnic DNA test?
Institutions that engage in such research guarantee complete confidentiality and high quality of the research. Special clinics and laboratories allow people to take a DNA test for ethnicity.
You can conduct a test on remote access and send the genetic material by mail. Services are paid by credit card, and the results can be obtained by mail.
Test
People who choose to do this kind of research are interested in how they do a DNA test for ethnicity. The test subject will need to pass the genetic material and submit it to the selected laboratory. The cost and speed of the test result depends on the volume of the study. A full genetic examination can cost hundreds of thousands of rubles, and the study of one gene costs about 1,000 rubles.
The specialist extracts DNA from the sample and conducts the study. The results are compared with data from the haplotype reference database . The researcher identifies ethnic groups with which there is a connection on the paternal or maternal side. The specialist then interprets the results and provides the client with a history of the genus. If a person has a mixed origin, the researcher makes a detailed breakdown, which allows you to see the genes of different nationalities in percentage terms.
Public opinion
Reviews of the DNA test for ethnicity are mixed, as some people see this as a real scientific breakthrough, while others claim that the information received is very vague.
Some comments indicate that the study provides accurate results only regarding race. Reviews report that this test should not have high expectations, since genetic data cannot be considered as a reflection of ethnicity or nationality.
Brief conclusion
Using DNA analysis, which allows you to find out ethnic origin, you can find out about their distant ancestors. One half of the DNA is inherited from the father, and the second from the mother, so the genetic code consists of a complex mosaic.
Various changes in their structure, as well as random mutations accumulate from one generation to another. DNA research allows you to separate ethnic groups from each other, provide data on the family tree. Such an analysis allows you to look deep into the centuries.
