Research of ethnic origin (genealogical analysis)

In the modern world, the relevance of this topic is of great importance for many fields of science. In particular, in genetics and medicine, genealogical analysis allows you to establish kinship between individuals, identify hereditary diseases and the risks of their spread in the family. The research is also used to study evolutionary processes and develop new methods of treating genetic diseases.

Genealogical analysis or "Ethnic Origin" test is a DNA test of patients to study the ethnic origin, geographical roots and migration routes of the family. Genealogical analysis allows you to establish, explore your ancestry and find out the history of your family. The method is based on the study of unique genetic markers that are passed down from generation to generation.

Indications for use

Patients' interest in their own ancestry is growing every day all over the world. These issues become even more relevant when undergoing treatment with assisted reproductive technologies.

After all, when using donor genetic material (donor eggs, sperm) for the treatment of infertility, it becomes possible to learn not only the phenotypic characteristics of the donors reproductive cells, but also to find out one's own ethnicity and find a donor of a similar ethnic group.

These are the answers patients are looking for:

learn about their ethnicity,
find distant family ties,
confirm or deny family memories of migration from other countries,
understand your identity.

Advantages of the procedure

Ethnicity tests - are methods of establishing ethnicity through DNA testing.

We have three types of such studies for you:

Analysis of ancestry on the male (paternal) line - Test "Ethnic origin" on the male line Y chromosome.
Analysis of ancestry on the female (maternal) line - Test "Ethnic origin" on the maternal mtDNA line.
Analysis of ancestry on the male (paternal) line and analysis of ancestry on the female (maternal) line - Test "Ethnic origin" on the male line Y-chromosome and on the maternal line mtDNA.

Two types of DNA are particularly important for genealogical research:

Y chromosome: Transmitted only through the male line (from father to son).
Mitochondrial DNA (mtDNA).: Transmitted through the maternal line (from the mother to all children).

Such markers allow you to trace your ancestry through paternal and maternal lines.

Haplogroups

Haplogroups are a group of similar haplotypes that share a common relative who had a mutation that was passed on to all descendants.

Distinguish:

Haplogroups of the Y chromosome: Represent the paternal line.
Mitogroups of mtDNA: Represent the maternal lineage.

Haplogroup determination allows you to identify the ethnic origin and geographic regions where your relatives came from thousands of years ago.

Results of the study

After studying the data, the specialists compile a detailed report that includes:

Definition of a haplogroup;
Ethnicity;
Geographical regions of origin of relatives;
Possible migration routes;
Time of origin of the haplogroup;
Geographical region of distribution of haplogroup carriers at the present time.

Preparation and course of the procedure

The test material for the Ethnicity test is a swab from the inside of the cheek (buccal epithelium).

The turnaround time is 10 days after the laboratory receives the samples.

Features of the procedure

As a result of ethnicity testing, it is possible to confirm genetic kinship with historically known individuals.

In some cases, genealogical analysis can reveal a relationship to historically famous individuals or even royal dynasties.
