Czech Republic: haplogroups
FamilyTreeDNA has 2,371 kits with a Y-DNA result and 1,198 kits with mtDNA (mitochondrial DNA). On the paternal line the most common are R1a-Z282 — 30%, R1b-L51 — 21% and I2 — 9%. On the maternal line the most common are H — 40%, U — 19% and T2 — 9%. YFull has 254 samples for Y from the same area, and its mix of major branches is almost the same. The largest gap is R1b-P312: 10% on FTDNA against 16% on YFull.
Compare with…Mitotree, the mt tree of FTDNA Discover, has about 100 more samples from here that the public mt tree lacks: mostly academic studies, GenBank among them (copy of 11 November 2026). This page is built from the public FTDNA tree.

Migration paths of the characteristic branches #
Paths of the region's main characteristic branches, as modelled by FamilyTreeDNA Discover, on one calendar clock: in each year a branch stands where its ancestral line was. Grey is a stretch of path shared by several branches; the large marker is the branch itself. Above the map you can pick the paternal line (Y-DNA) or the maternal one (mtDNA).

The same country on YFull #
The same country at the second company, YFull. Its samples are placed on the FTDNA tree by shared mutations, so the branches are comparable. FTDNA share on the left, YFull on the right, then the difference in percentage points. Republics and other sub-regions are taken out of the country, as at FTDNA. Starred branches are nearly empty at YFull: every test there is whole-genome and reaches the fine branches. Only YFull customers (YF number) are counted, no ancient DNA. YFull data of 2026-11-02. The tree shows only its top three levels.

Native language reported by YFull customers from this country. People from regions with a page of their own (republics, autonomies) are shown there. These are the testers' own answers, not a census.

Recent kin across borders #
Shared young paternal branches: YFull customers from this country and from the partner country have a common paternal-line ancestor no older than 500 years. The comparison accounts for how linked a country is abroad overall: shown are partners with more shared branches than its general openness would give. It reflects recent migration and shared ancestry, not ethnicity.
Paternal and maternal lines together #
Members of this people with both lines known on YFull. For each “Y branch × mt branch” combination, how many times it occurred and how many would be expected if the two lines had nothing to do with each other. Y and mt pairs → n=94
Most frequent combinations
Ancient relatives of male lines #
Which cultures of the Copper Age and Early Bronze Age (4000–2000 BCE) the local male lines lead to most closely. The share is how many kits lead to a culture; the range is in brackets.
- Fatyanovo–Balanovo culture and Bell Beaker culture fragileshared branches: R-M417, R-P310, N-CTS6967
in the same bar: Neolithic Scandinavian, Corded Ware, Seima-Turbino culture59%(52%–72%) - No close ancient relativesalso cultures under 3% and kits with shallow tests41%
How it is counted
- Branches of the era. We take the ancient samples whose date falls inside the era, and compare the lines as they stood 1,500 years before the era ends.
- A culture’s profile is the share of its lines on those branches. The number of samples does not change a weight: a culture of seven men weighs as much as one of a hundred and twenty.
- A shallow test. An ancient man typed above the cut is spread over the branches under his node, by how many men each holds now. Today’s kits are treated the same way.
- Who is admitted. A culture takes part when its sharply typed men cover 25% of the population on their own: branch by branch we add the smaller of the two shares, the culture’s and the population’s. One dug within 550 km needs only 0.5%.
- The shares. We pick the weights of the cultures so that their mixture comes as close as it can to today’s set of branches.
- Look-alike cultures. When cultures share almost all their branches, the data cannot say whose kin the men are. So we do not split the share between them: they get one bar.
- The range. We recount everything on random subsets of the samples. In brackets are the bounds the share keeps in nine runs out of ten. A share that can fall below 5%, or below half of itself, is not shown at all.
- “Fragile”: the share rests on a few samples, or a random shuffle of cultures gives as much.
What it does not mean. This is kinship of male lines, not the origin of a people. The female lines say nothing here. Who takes a test is a matter of chance, so the shares compare between countries, not with a census.
Other eras: Early Middle Ages — Avars 31%.
