O-PK4
O-PK4 is a branch of the FamilyTreeDNA Y tree with 506 kits that gave a country, counting all sub-branches. Almost all of its kits sit in a single sub-branch, O-M95, so this branch gets no conclusions of its own. It is most common in these samples: Indonesia (55% of kits), Vietnam (19% of kits), Malaysia (15% of kits). The branch's common ancestor lived about 14k years ago: the FTDNA Discover estimate runs from 12k to 16k years ago. YFull has 196 samples in this branch and dates its common ancestor to 13k years ago.
Where it is found #
Countries and regions given by the branch's carriers. “Share of branch” is the part of the branch's kits that belongs to the country. “Share of country” is the part of that country's kits that falls into the branch; it is computed only for countries with at least 50 kits.

Most common among these peoples #
From YFull samples that gave a mother tongue: the part of a people's samples that falls into this branch. Peoples with at least 3 samples in the branch are listed.
- Mandarin Chinese: 2.4% of samples (3 of 125)
Sub-branches #
Sub-branches that have their own page (50 kits or more). The bar is the kits in the sub-branch with its own sub-branches; the age is when its common ancestor lived.
1 small sub-branch more without a page: 6 kits. On the branch itself, without a resolved sub-branch: 5 kits.
Surnames #
Surnames that testers entered at FTDNA, over the whole branch with its sub-branches: 3 distinct among 6 kits. FTDNA gives surnames per branch only, with no country attached, so they cannot be split by country.
- Advincula 2
- Sastrosudharmo 2
- Thieu 2
The same branch on YFull #
YFull builds its tree from the same SNPs; the node is matched by name or by a shared SNP. TMRCA is when the common ancestor of all samples lived, formed is when the branch split from its parent. Intervals are 95%.
O-PK4: 196 samples. The common ancestor lived 13k years ago (12k–15k); the branch split off 23k years ago (21k–24k).
