The following content was translated from DNA in TNG

TNG 12.1 has significantly improved the possibilities of managing genealogical DNA data. TNG is likely to be the program that currently best integrates DNA data into a genealogical database. A little guide may help.

Basically, a distinction has to be made here between (a) information on tests of yDNA and mtDNA and (b) matching based on atDNA on the, whose input / administration must be somewhat different.

Basics

All DNA tests can be accessed in the Administrator login via "Administration" / "DNA Tests".

TNG distinguishes between "DNA tests" and "DNA groups". Several individual "DNA tests" can be assigned to a "DNA group". Above all, "DNA groups" are mainly important for the administration of atDNA matches (and less for yDNA tests); so they could be renamed individually to "matching group" or similar.

If you open the submenu "DNA Tests", three tabs are visible: "Search" (in already existing "tests"), "Add" (self-explanatory) and "DNA groups". If you open this tab "DNA groups", you can search in groups, create groups - or switch back to the DNA tests.

yDNA

To add information about an yDNA test, go to "DNA Tests", "Add" and then get a first data mask. Under "Test Type" select "yDNA"; the other input fields are self-explanatory. Even here, the test can be linked to the subject who is either created in the DB itself as a person or can only be named (if he is not present in the DB).

After the first save, the data mask expands to allow entry of specific information about this DNA test, all the way down to a listing of the values ​​of all tested STR markers. It is important to separate single values ​​with commas without spaces and multiple values ​​with hyphens. Whether it is really necessary or sensible to store the data at this level of detail must be decided individually with regard to data security. The detection of the STR markers may be useful, e.g. manages a larger family name project because TNG makes it possible to compare multiple yDNA tests and their STR markers. Matches and deviations are then quickly visible. However, it only makes sense if there are several tests of subjects that are possibly related to each other directly in the male line. It is not fruitful to compare the yDNA of people who are not directly related.

"Persons associated with the test" includes, if you wish, all relatives of the subject in direct male line (trusting that the direct male line is not interrupted by some unknown paternity elsewhere). Of course, you can also include only those persons whose direct relationship through (then several) tests is also proven.

mtDNA

To create a test of the mtDNA, one proceeds in the same way as with the yDNA: One selects "Add" under "DNA tests" and receives then a first data mask, where as test type "mtDNA" is to be selected. Again, a first link is possible.

After saving, the data mask also expands here to capture details about the mtDNA. Here you can select a reference DNA (RSRS or rCRS) and then enter all the individual deviations from this reference DNA. Again, one must consider whether it is useful and necessary to capture the data in such detail or whether the naming of the haplogroup is insufficient.

By "persons associated with the test", one binds, if one wishes, all relatives of the subject in a direct purely female line or only those persons whose direct relationship through (then several) tests is also proven.

atDNA

AtDNA is all about the agreement of shorter or longer DNA segments between two or more people, the so-called matches. Therefore, in the case of atDNA (unlike yDNA and mtDNA), it is not the single DNA test that is the essential reference but the respective DNA match, defined in each case by two subjects who have at least one common DNA segment.

Conceptually, a distinction must be made here between the actual subject (one or another person whose DNA tests are administered) and those other persons who have also carried out a DNA test and who are included in the relevant databases (Ancestry, MyHeritage, FTDNA , Gedmatch) appear as a match (hereafter called "Person with DNA Match").

The following procedure is recommended:

First, a "test group" is created for the actual subject, which is named accordingly (for example, "atDNA Hans Mustermann").

Then add a new "DNA test" for each DNA match. The term "DNA test" is then somewhat misleading, but programmatically not to change due to the variables used; what is meant is the person's DNA test with a DNA match.

To do this, select "Add" under "DNA Tests", then "atDNA" as "Test Type" and carry - important! - as a "tested person" just that other person with a DNA match, with whom the subject has at least one common DNA segment. Then assign this "DNA test" to the just created "test group".

As an example: The proband Hans Mustermann has common DNA with Berta example and Eduard example. The test group is "atDNA Hans Mustermann". Then one adds a "DNA test" with Berta Beispiel as "tested person" and one with Eduard Exempel (and gradually with another hundred people with DNA match).

Next, a "test group" is created for the actual subject, which is named accordingly (for example, "atDNA Hans Mustermann").

Then add a new "DNA test" for each DNA match. The term "DNA test" is then somewhat misleading, but programmatically not to change due to the variables used; what is meant is the person's DNA test with a DNA match.

To do this, select "Add" under "DNA Tests", then "atDNA" as "Test Type" and carry - important! - as a "tested person" just that other person with a DNA match, with whom the subject has at least one common DNA segment. Then assign this "DNA test" to the just created "test group".

As an example: The proband Hans Mustermann has common DNA with Berta Beispiel and Eduard Exemple. The test group is "atDNA Hans Mustermann". Then one adds a "DNA test" with Berta Beispiel as "tested person" and one with Eduard Exempel (and gradually with another hundred people with DNA match).

After the first save, more details about this DNA match can be captured. Important here are the common DNA in cM, the number of segments and information on the largest common segment (chromosome, position, SNP). Under "kinship" one enters as "possible range" those kinship degrees, which can be derived from the shared cM project of Blaine Bettinger and under "actually" just the actual kinship degree, if it has been determined.

The indication of a farthest ancestor is not useful in the atDNA (this refers to the yDNA and mtDNA). If the common ancestor or common ancestor pair of the subject has been identified with the person with DNA match, this ancestor or ancestor pair can be linked to the DNA test.

Further links are possible below under "Persons connected with the test": Here you select all persons, who make the connection first ascending from the subject to the next common ancestor (pair) and from there descending again to the person with DNA Match ("tested person") - if it is included in the DB.

Display of DNA data

In the person view, all DNA tests that have been linked to the respective person are displayed (yDNA, mtDNA, atDNA). In this way, it can be determined at a glance whether a person is also confirmed by a DNA test and which DNA segments come from this person. It is also easy to track the origins of individual segments over generations.

It is also possible to select the "DNA tests" section under the user view on the start page and then display all DNA tests of the group "atDNA Hans Mustermann". Individual "DNA tests" (or matches) can be selected and compared in detail (via "Compare Selected"). In this way, the genealogical database makes it possible to understand exactly which persons have detectable DNA compounds or which DNA segments are already determined.

Labeling of persons confirmed with DNA

For a quick overview and illustration, which people of the pedigree or which lines are confirmed by DNA tests, I have developed the following solution: A small graphic with a DNA symbol is linked to the person in question and there each as a "standard photo" displayed (except for the first generations, where there are also photos for the persons concerned, these photos have priority for me). Then in pedigrees, kinship surveys, etc. is always immediately recognizable what is confirmed by DNA and what not.
