It is a test that not only lets you know your parental lineage (Y-DNA), but also your deep genetic mutation that falls below your parental lineage (Y-DNA).

Over time, other sub-lineages branch from each major patrilineal genetic lineage. Such sub-lineages are given codes for distinction from other genetic sub-lineages, so that each lineage represents an independent mutation under the same major patrilineal genetic lineage. Again, over time, more sub-mutations branch from such sub-mutation, and so on.

And this genetic mutation is the deep sub-mutation that in DNA & US we call (Deep Y).

Y is an abbreviation for the Y chromosome that a person inherits through his father through the paternal line, and Deep means a mutation below the main paternity line (major Y-DNA), where it is abbreviated (Deep Y).

While the general rule is that a father bequeaths his genetic lineage (Y-DNA) to his son without a change, and the son bequeaths the same patrilineal genetic lineage to his son (grandson) without a change and so on without end, over time, a type of sub-mutation emerges under the same original patrilineal genetic lineage. Due to this mutation, other sub-lineages branch from each major patrilineal genetic lineage. Such sub-lineages are given codes for distinction from other genetic sub-lineages, so that each lineage represents an independent mutation under the same major patrilineal genetic lineage, and other sub-mutations branch over time from the sub-mutation and so on.

These sub-mutations have a shorter age than the patrilineal genetic lineage. For example, if the major patrilineal genetic lineage is 10,000 years old, the mutation age will be 5,000 years and it will result in other mutations of shorter ages, and so on.

Your share of the same genetic lineage with anyone decisively means that you meet in a common grandfather who represents the biological father of your genetic lineage and who lived in a period equal to the age of this genetic lineage. But this does not mean that this person is a close paternal cousin to you.

This is where the benefit of deep sub-mutation testing (Deep Y) comes in, because sub-mutations under the major Y-DNA have a shorter age than this major Y-DNA. For example, if the major major Y-DNA is 10,000 years old, the mutation age will be 5,000 years and with the succession of generations, other mutations will emerge from these mutations at shorter ages.

And testing the deep branch of the paternal genetic line (Deep Y) will let you know which users are positive for the mutation and with whom you meet in a common ancestor who lived at an age equal to that mutation.

In this way, you will be able to discover the relatives with whom you meet in a common ancestor on the patrilineal line that lived as recently as 200 years ago only or less.

That is why we always say that the Y-DNA test allows you to understand your anthropological affiliations, But Deep Y test allows you to understand your affiliation within the time frame of lineages and families.

No, but you must do this test at any third party that provides this type of test, and then upload the results to the DNA & US platform.

First you will be able to find out what deep sub-mutation (Deep Y) you belong to, and secondly during the current time, there are many people who share the same deep genetic mutation with you. Through this feature, you will be able to know these people and places of their expansion, and other information that will allow you to understand more about your sub-mutation and its expansion at the present time.

This does not mean that the result is different, each company may differ in the approved reference to the same deep sub-mutation, this mutation may be indicated by a specific code in a particular laboratory, while it is indicated by a different code in another laboratory, although the mutation is the same.

Some users will see an asterisk (*) next to the result of the (Deep Y), which means that this encoding is not final and is subject to change. But this does not mean that the result is not complete or that it is subject to change. The result is the same and fixed, but this means that the code itself is not final and modifiable.

This means that you and he meet in a common ancestor that lived before a period of time equal to the age of your (deep Y).

For example if the age of your parental sub-mutation (Deep Y) is (300 years) and another user appears in the matches below the same parental sub-mutation; This mean that you and he meet in a common paternal ancestor on the paternal line lived during this period (300 years as in the previous example).

They are approximate lifetimes and are constantly evolving according to the latest research and the evolution of our database.

The appearance of any user below your (deep Y) necessarily indicates that he is close to you on the paternal line, and the age of meeting between you is undoubtedly equal to the age of this mutation (deep Y) at most. As for the fact that you and he belong to two different population groups, this does not negate your kinship anyway.

There is no single reason that explains this, as the possibilities in this field are wide open, and this opens the door for you to search and investigate to reach an explanation for this.

We consider such surprises to be a secret in your DNA that no one but your DNA will tell you, so you are lucky because you have found a relative who lives in another area, and you can communicate with him and exchange information with him about it.

This means that until now no user of ours has the same deep sub-mutation (Deep Y) as yours.

Note that hundreds of samples are added every month, which leads to the growth of our database day by day, and if there is a match, it will appear to you automatically, so be sure to visit your matches page from time to time to find out what is new.

This means that you and he meet in a common ancestor that lived before a period of time equal to the age of your (deep Y).

For example if the age of your parental sub-mutation (Deep Y) is (2500 years) and Historical or ancient figures appears in the matches under the same parental sub-mutation; This mean that you and he meet in a common paternal ancestor on the paternal line lived during this period (2500 years as in the previous example).

No, not necessarily, but it means that you are cousins on the paternal line and meet in a common ancestor which is the same deep mutated mutation.

However, this character may already be an ancient ancestor of you specifically on the line of paternity, but this is rare, and in this case we advise you to take the antique DNA Package, if this character appears in the match list as an ancient ancestor, in this case you will have two options, first: That this character is indeed your ancestor on the line of paternity, and the second: that this character is an ancestor of you but not on the line of parenthood.

If this character appears to you in the matches list, but not as an old ancestor, but as an old relative of yours, or this character does not appear to you at all in the matches list, in this case it can be confirmed that this character is not an ancestor of you on the line of paternity.

This question has been answered in detail in the ancient DNA Test FAQs section, so we recommend that you review this file.

This means that until now no historical or ancient figures of ours has the same deep sub-mutation (Deep Y) as yours.

Note that samples of historical and ancient figures are added periodically, which leads to the growth of our database day by day, and if there is a match, it will appear to you automatically, so be sure to visit your matches page constantly to find out what is new.

As is the case with the testing of the patrilineal genetic lineage (Y-DNA), only males can take testing of the deep sub-mutation or download their results. For females, they cannot do this. So, if a woman wants to know the deep sub-mutation of its male ancestors, the testing must be taken by her father, paternal brother, paternal uncle, or other relative she meets on the paternal line.
