A Y-DNA SNP test determines your Y-DNA haplogroup. Knowing how you connect to other people on the Y-tree can help narrow geographical origins and can potentially confirm specific genealogical connections. We encourage you to test as many SNPs as possible for [...]
Yes. It is possible that a SNP will back mutate (change back). However, SNPs are slow changing. Thus, back mutations are uncommon.
Please order SNPs with the help of an expert if you aren't sure which SNP(s) will benefit your research. Before ordering, you should ask the advice of an expert on your haplogroup and subclade. We recommend joining an appropiate Y-DNA haplogroup [...]
Can I skip extensive SNP testing and just test for a downstream Advanced Order SNP? If I am positive, may I assume that I also have all the SNPs above it?
It is possible to order Advanced SNPs in this way. We advise that you do not unless another closely related male from your surname group has already taken a more advanced SNP test such as the Geno 2.0 or Big Y. [...]
How many SNPs does the Family Finder program use to determine an Identical by Descent (IBD) segment?
The Family Finder program declares a DNA segment to be Identical by Descent (IBD) if it contains at least 500 matching SNPs (Single Nucleotide Polymorphism) in series. Note: This has not changed with the conversion to the Illumina Omni platform.
Are Y-chromosome DNA (Y-DNA) SNPs ever related to recent times and genealogy? Are they always for historic periods and more ancient ancestry?
Y-chromosome DNA SNPs (single nucleotide polymorphisms) are not always from anthropological or even historic times. Some Y-chromosome DNA SNPs are restricted to a single family that is related in genealogical times (one to 15 generations). These are family SNPs or [...]
A SNP is a single nucleotide polymorphisms. That means that it is a single small change in your DNA code. These changes are rare. Once they happen, they seldom change back (back mutate). An STR is a short tandem repeat. [...]
The GAP - Project Profile page is one of the Group Project Administration pages. Group Project Administrators use this page to enter (and edit) their Group Project's description and to control settings and banner/profile images for the project's website. Additionally, [...]
You may utilize the Members Subgrouping tool to create, manage, and delete subgroups. You may also add and delete project members from subgroups. You can enter participants into one subgroup, and you can choose a background color that will [...]
A Y-DNA test looks at male inherited Y-chromosome DNA (Y-DNA). The Y chromosome is passed on from a father to his sons. Thus, it is only found in males. Y-DNA testing can then be used to trace clearly a direct [...]
Here at FamilyTreeDNA (FTDNA), we want to provide our customers with the highest level of Y-DNA haplogroup confidence, so we created our SNP Assurance Program (which began with test batch 173). With the SNP Assurance Program, if we cannot predict [...]
Once we receive your DNA sample, we send your sample directly to the lab for processing. You will also receive a notice of receipt via the email address associated with your account. Processing times vary depending upon the test(s) [...]
All of our kits go through the same basic process once we have the sample in our lab. Here are some of our most common questions about your test status and what we do with your sample. [...]
You will find answers to our most common questions on this page. Explore the rest of the Learning Center to find answers to more complicated issues by clicking the menu bar above. Before I Buy You may learn more [...]
The Big Y Block Tree is a vertical-block diagram of the Y-DNA Haplotree showing the relationships between you and other Big Y testers. This tool helps you visualize how the paternal lineages of you and your matches are related to [...]
The Chromosome Browser is a feature of our Family Finder autosomal DNA test. This tool allows you to view and compare the DNA segments that you share with your Family Finder matches. Click image for a closer look. [...]
Discover the countries of origin and surnames for each branch of the world’s largest Y-DNA Haplotree, comprised of more than 20,000 branches, 150,000 variants, and 170,000 confirmed SNPs from our Y-DNA database. Navigating the Public Y-DNA Haplotree To navigate [...]
FamilyTreeDNA is an online service. Therefore, all results provided by FamilyTreeDNA will only be available online and accessible via a computer or mobile device with internet capabilities. Results will not be mailed, and we will not issue refunds for tests [...]
