Scotland Y-DNA

FamilyTreeDNA holds for Scotland: 14,176 kits with a Y-DNA result. On the paternal line the most common are R-S744 — 6%, R1b-L151 — 5% and R1b-L21 — 4%. YFull has 1,040 samples for Y from the same area, and its mix of major branches is broadly the same. The largest gap is I-L137: 2% on FTDNA against 5% on YFull.

Big Y

rough share of kits with a Big Y test, a full read of the Y chromosome. It is estimated from the branches where the region's kits sit, so it is an estimate, not a count.

Each colour is one of the eight most common macro-haplogroups worldwide (the first letter of the haplogroup, such as R or J). Everything else is grey.RIJENGQTother

Major branches (clades) #

The major branches the region's kits belong to. Each kit is counted once, in the finest major branch its test reached. Asterisk: kits left on the branch itself because they fall into none of its major sub-branches. A branch counts as major when it holds at least 0.4% of all kits worldwide.

Key branches tree #

Tree of the main branches. Each branch counts every kit in it and in its sub-branches; sub-branches are indented. Branches of at least 1% of the sample are shown; pass-through branches with no side branches are skipped. Age is how many years ago the branch's common ancestor lived (TMRCA), from FTDNA Discover.

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 2026-09-29.
