Thanks to numerous reality shows on domestic television, many people know about modern methods of establishing kinship between people. Expression: DNA test on the Y chromosome - can be heard in these programs quite often, but limited airtime will not allow fully deciphering this medical term. Let's fill the information gap and reveal what exactly breaks down under this professional abbreviation.
More about the Y chromosome
Human DNA includes a whole set of elements responsible for its development. These include the Y chromosome, which is transmitted exclusively through the male line, and changes in it can occur only as a result of mutations. It was they who led to the fact that at present more than 300 groups have been singled out on earth only for this genetic indicator. Belonging to a certain group allows you to determine:
- National factor.
- Relationship in the male line.
- Ethnicity.
Establishment of kinship, nationality (ethnos) can be carried out only along the male and not necessarily in a straight line. For example, to establish paternity between a male child, it is not necessary to compare his biological analyzes with those of the father. They can be quite successfully replaced with samples taken from a grandfather, uncle, or alleged brother. If the relationship exists, then the analysis carried out on the Y chromosome is guaranteed to show a 99.9999% positive result. Samples of a decade or even a hundred years ago are quite suitable for it (bones, hair with a root bulb, teeth or dentures).
You can get more detailed information and find out how you can get an analysis for a DNA test on the Y chromosome using the official website of a medical laboratory that provides this type of service for everyone on a commercial basis. Biological material for all the necessary research can be taken independently and sent by mail. Detailed instructions are presented online in the corresponding section of the Internet resource.
