Uruguay: haplogroups

FamilyTreeDNA has 17 kits with a Y-DNA result and 17 kits with mtDNA (mitochondrial DNA). That is too few for a summary: with fewer than 50 kits the percentages are shaky, and the site draws no conclusions from them.

Compare with…

Mitotree, the mt tree of FTDNA Discover, has about 38 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.

Paternal line · Y-DNA

17 kits · 2 branches
Main branches of the Y tree. Each branch counts every kit in it and in its sub-branches; sub-branches are indented. Age is how many years ago the branch's common ancestor lived (TMRCA).
R1b-DF27
8 · 47% (8 of 17, 95% confidence interval: 26–69%) 4,700 years
J2
3 of 17 (3 of 17, 95% confidence interval: 6–41%) 28k years
other
6 · 35% (6 of 17, 95% confidence interval: 17–59%)

Among the rest: I 2, Q 1.

Maternal line · mtDNA

17 kits · 3 branches
Main mt-tree branches grouped by letter, sub-branches indented. Each branch counts every kit in it and in its sub-branches. Age is how many years ago the branch's common foremother lived, from FTDNA data where available.
H1
4 of 17 (4 of 17, 95% confidence interval: 10–47%) 7,900 years
L1
3 of 17 (3 of 17, 95% confidence interval: 6–41%) 111k years
U
3 of 17 (3 of 17, 95% confidence interval: 6–41%) 51k years
other
7 · 41% (7 of 17, 95% confidence interval: 22–64%)

Among the rest: B 2, C 1, D 1.

YFull

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.

Y-DNA

YFull has fewer than 30 samples from this country, too few to compare. 2 samples on YFull

mtDNA

YFull has fewer than 30 samples from this country, too few to compare. 4 samples on YFull

Ancient samples

From excavations on this territory: 0 samples by Y-DNA and 1 sample by mtDNA.
