FamilyTreeDNA holds for Northern Ireland: 2,970 kits with a Y-DNA result and 614 kits with mtDNA. On the paternal line the most common are R-Z39589* — 5%, I-L137 — 5% and R-S588 — 4%. On the maternal line the most common are J1c — 9%, U5b — 4% and K1a — 4%. YFull has 240 samples for Y from the same area, and its mix of major branches is noticeably different. The largest gap is I-CTS595: 1% on FTDNA against 6% on YFull.

73%
agreement with YFull · Y
how closely the Y major-branch make-up matches between FTDNA and YFull. 100% is identical, below 80% is visibly different.
I-CTS595 +5.5
gap to YFull · Y
the Y branch whose share differs most between the two companies: FTDNA 0.7%, YFull 6.3%
30% / 36%
reached the finest branch: YFull / FTDNA
share of YFull samples and FTDNA kits that reached the finest branch of the FTDNA tree. On average a YFull sample sits 42.4 branchings from the root, an FTDNA kit 41.9
36%
Y-DNA · on leaves
share of kits that reached the finest branch of the tree. The rest stopped at a broad branch: their test was not detailed enough.
58%
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.

mtDNA · on leaves
share of kits that reached the finest branch of the tree. The rest stopped at a broad branch: their test was not detailed enough.
0.21
mt to Y
maternal-line tests per one paternal-line test. Below 0.3 means the country tests almost only the male line.
