Paternal Origin Test
The paternal lineage DNA test, also known as the Y-DNA test, allows for the exploration of a very specific branch of your ancestry: the lineage of men in your family.
How does it work?
Order online
Order your DNA test online and add your options if necessary.
Receive your DNA kit
After your online order, the laboratory sends you a saliva collection kit directly to your home.
Collect samples at home
Easily perform your home sample collection using a simple buccal swab to collect a saliva sample.
Send to the laboratory
Place your samples in paper envelopes and send them to the laboratory following the instructions provided in the email.
Receive Your Results
Receive your results by email in a few weeks.
How it works
-
Online order via the test link.
-
Receipt of the kit at home.
-
Buccal swab: you gently rub the inside of your cheek with the swab following the instructions (quick and painless).
-
Return of the sample to the laboratory according to the instructions.
-
Genetic analysis and comparison with databases.
-
Receipt of results (often via email, sometimes also in printed form depending on the option).
Who is this test for?
-
Only men can directly undertake this test, as they are the only ones who possess a Y-STR. The test relies on the analysis of the Y chromosome, which is transmitted almost unchanged from father to son across generations.
The advantages of Y-DNA testing
-
It allows for tracing back very far into the past on a specific male lineage.
-
It identifies your Y haplogroup and aids in understanding your paternal origins.
-
It facilitates targeted comparisons and may reveal unknown familial connections.
Y Haplogroup
Haplogroups are large genetic branches that represent the primary divisions of humanity over extended periods.
During a Y-DNA test, the haplogroup is identified from mutations (SNPs) passed down from a common male ancestor.
Thus, two men sharing the same haplogroup have a very ancient paternal lineage. Certain haplogroups being more prevalent in specific regions allows for the connection of your lineage to an ancient geographical origin.
What is the purpose of a paternal lineage DNA test (Y-DNA)?
Verify a Male Relationship Link
You can compare your Y-DNA with that of another man to determine whether you share a common male ancestor.
This is useful for confirming paternal lineage, exploring the origin of a surname, or clarifying a situation where records are incomplete (undocumented adoption, genealogical uncertainty, uncertain branch).
Discover the geographical origin of your paternal ancestors
The test makes it possible to identify your Y haplogroup: a major branch of the male family tree associated with ancient populations and geographical areas (Europe, Africa, Asia, etc.). This helps to place your lineage in time and space, sometimes over tens of thousands of years.
Unlocking a branch of your family tree
When a lineage is “blocked” due to lack of documents, Y-DNA can help you find matches in databases, find distant cousins, and obtain new research leads, including through collaborative projects by country, family name, or haplogroup.
