Levels C and D are replicated, but there is no evidence that knowing them improves an outcome: that is why the report does not open with them.

0.8% unassigned. Segments that do not resemble any reference population closely enough to be assigned with the required confidence. That this percentage exists is a good sign: the method would rather stay silent than make something up.

The detail, as far as the panel supports it

Each row is a different portion of the genome, and they do NOT contain one another: “Iberia” is not inside “Southern Europe”, they are two separate pieces. When a row says “no region determined”, that piece was recognized as belonging to the continent and could not be narrowed further: it is the weakest claim in the table, even though it has some of the longest bars.

What this panel cannot distinguish

Galicia and Andalusia, the two regions that sent the most people to Argentina, sit inside this group together with Castile, Aragon, Extremadura, Cantabria and Murcia. With this panel there is no way to separate them.

What this panel cannot distinguish

The reference panel contains no population from the Southern Cone: its only American references are Mesoamerican and Amazonian. A Guaraní, Andean or Patagonian component has nowhere to fall, and is reported under the closest label available, which may be thousands of kilometers away. Read it as “Indigenous American, region not determinable” and not as a specific origin.

Unassigned stretches

8.6%

The stretches the method could not assign to any continent with the required confidence. This is not the same as “no region determined”: there, the continent is known. This is neither redistributed among the others nor hidden — the fact that it exists is what makes the rest readable.

Across 847 genome stretches, at a per-stretch confidence threshold of 0.60.

Neanderthal ancestry

The modern humans who left Africa interbred with Neanderthals, and that stretch stayed in the genome of their descendants. Almost everyone outside Africa carries some: it is not an oddity, it is part of the shared history.

How to read these percentages

The Indigenous American component is estimated with lower resolution than the European one: the reference panels for South American Indigenous populations are considerably smaller. The percentages are estimates with uncertainty, not exact measurements, and they are not equivalent to cultural identity, ethnic identity, or belonging to a people.

The journey of your lineages

Each line's path down to your result, told stop by stop. Dates are estimated ranges from the peopling literature.

Why it is a single line

Mitochondrial DNA travels only along the magenta line; the Y chromosome, only along the blue one. That is why they are two codes and not a percentage: each tells of a single ancestor per generation.

Maternal line
Mitochondrial EveAfrica · 150–200 thousand years ago
Every living mitochondrial lineage descends from a single woman. She was not the only one of her time: she is the only one whose line of daughters reached today.
DD~18,000 years
D is one of the five founding lineages of the Americas. It came out of northeastern Asia, crossed Beringia some 15,000 to 20,000 years ago, and moved down the continent. The D1j branch is characteristic of the Southern Cone and is found at high frequency in Indigenous populations of central and southern Argentina and of Uruguay.
D1Your exact branch
The code reads like chapters: D is the major branch, and each following letter or number is a more recent split within it. D1 is your exact twig — the women who share it today descend from one same mother, far more recent than the branch as a whole.
Paternal line
The Y common ancestorAfrica · 200–300 thousand years ago
Every living Y chromosome descends from a single man, by the same reasoning: the only line of sons that never broke.
R1bR1b~6,000 years
R1b-M269 is the most frequent paternal lineage in Western Europe: it predominates in the Iberian Peninsula, France, Ireland, and the British Isles. It expanded with the population movements of the Bronze Age. In Argentina it almost always arrives through Spanish and Italian immigration of the 19th and 20th centuries.
R1b-M269Your exact branch
The code reads like chapters: R1b is the major branch, and what follows names more recent splits. R1b-M269 is your exact twig — the men who share it today descend from one same father, far more recent than the branch as a whole.
