Y-DNA Paternal Line Report
Frequently asked questions (FAQ) and answers about Genomelink's Y-DNA Paternal Line Report
29 articles
- Your report shows a region my recent family isn’t from — is it wrong?Usually not — deep paternal regions describe antiquity, not where your recent family actually lived.
- Where does the data come from?The open scientific datasets, public Y-tree resources, and ancient-DNA literature behind your report.
- How often is the report updated?How we refresh the dataset, and how paid customers get updated reports automatically at no extra cost.
- My result doesn’t match my documented paternal genealogy — what could explain that?The usual causes — file coverage, a stray marker, and deep-time lineage — and when to contact support.
- Can my haplogroup change over time?Your biology can’t change — but our reading of it can get more precise over time.
- Why did my result change from an earlier version?Why a newer result is usually more accurate as we improve the calling algorithm and reference data.
- My file has extra markers that don’t match any named branch — what are those?What unrecognized derived markers in your file are, and why we don’t assign them without confirmation.
- Another test or website gave me a completely different haplogroup — a different main branch, not just a deeper one. Which is right?Why calls can differ across tools, how we check the markers, and how to send yours to us for review.
- My FamilyTreeDNA (or other Y test) gives a deeper or a different terminal branch — is your result wrong?Almost always a difference in depth, not a contradiction — the deeper branch usually sits below ours.
- How precise are the formation age and TMRCA dates?These are molecular-clock estimates with a margin — best read as “at least this old.”
- What do “Paleolithic,” “Neolithic,” and “Bronze Age” mean on my timeline?What the prehistoric time bands on your timeline mean, and the rough dates behind each one.
- Can I use this report for regular genealogy or to break through a brick wall in my family tree?Not directly — it’s a deep-history view of one paternal line, not a tool for tracing recent relatives.
- Why do you match me to ancient people instead of showing where my haplogroup lives today?Why we match you to published ancient specimens instead of mapping where your haplogroup lives now.
- Are the ancient “relatives” my direct ancestors — and why are some in places my family isn’t from?They’re distant cousins from deep time, not recent ancestors — and why their locations range so widely.
- Does my haplogroup tell me my nationality, ethnicity, or surname?No — a haplogroup is a deep-time lineage that predates modern countries, ethnicities, and surnames.
- Is my Y-DNA result the same as my ethnicity or ancestry percentages?No — Y-DNA follows one deep line while ancestry percentages blend all your lines. Both can be true at once.
- Will I find living relatives in this report?No — the relatives here are published ancient specimens, not living contacts to message.
- My father (or brother) and I both uploaded — should we get the same result?Yes, along the same paternal line — small depth differences just reflect how much each file covers.
- Can women get a Y-DNA report?Not from their own DNA — but you can use a raw file from a male relative on the paternal line, with consent.
- How accurate is the call?How we place you only on branches your markers support, showing both a confirmed and a provisional depth.
- What if my file doesn’t have enough Y-SNPs?What the free eligibility check does when Y coverage is too low — no charge, plus an upgrade option.
- Do I need to take a new DNA test?No — we read Y-SNPs from a 23andMe raw file or GRCh37 VCF you already have, so there’s no new test.
- What’s the difference between Y-DNA and mtDNA?How Y-DNA traces your paternal line and mtDNA the maternal line — two opposite single threads of your tree.
- Why didn’t my previous DNA tests report this?Why AncestryDNA, 23andMe, and MyHeritage didn’t show this, and what Genomelink surfaces from your existing file.
- How is this different from FTDNA Big Y?How our report differs from Big Y — your existing file and ancient matches, no new test, and when to upgrade.
- Does my report prove an unbroken father-to-son line going back thousands of years?Yes — your Y-chromosome is proof of an unbroken father-to-son line, with two caveats about place and dates.
- Does my Y-DNA result tell me anything about my health?No — this is a deep-ancestry report about your paternal line, not health, medical, or trait information.
- What do the letters and numbers in a haplogroup name mean, like R-M269?What the branch letter and the marker code mean, and why a longer code just means a deeper twig.
- What’s a Y-haplogroup, exactly?What a Y-haplogroup is — a branch of the paternal-line family tree defined by inherited Y-chromosome markers.
