Sierra Leone: haplogroups

FamilyTreeDNA has 33 kits with a Y-DNA result and 13 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…

FTDNA Discover holds about 50 more samples here that are not in the public tree, mostly from academic studies (estimate from the copy of 13 November 2026); this page is built from the public FTDNA tree.

Mitotree, the mt tree of FTDNA Discover, has about 99 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

33 kits · 3 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).

Among the rest: R 1.

Maternal line · mtDNA

13 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.

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 no samples from this country.

Data on this page: FamilyTreeDNA Y tree, 12 November 2026: 33 kits; FamilyTreeDNA mtDNA tree, 11 November 2026: 13 kits; YFull Y tree, 2 November 2026: 2 samples.
