Yes. It is possible that a SNP will back mutate (change back). However, SNPs [...]
No, the haplogroup names in mitochondrial DNA (mtDNA) do not correspond with the same [...]
Y-Chromosome DNA (Y-DNA) haplogroups and subclades names follow the conventions of the Y-Chromosome Consortium’s (YCC). The [...]

At Family Tree DNA, a Y-DNA haplogroup prediction is calculated using genetic distance. The [...]
Please order Advanced SNPs with the help of an expert. Before ordering, you should [...]
The following descriptions provide brief overviews of each haplogroup’s origin and geographic distribution.
No, you may first take the Geno 2.0 test and then transfer your results [...]
The Y-DNA tree begins with the common paternal ancestor to all men alive today. [...]
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 [...]
Are Y-Chromosome DNA (Y-DNA) SNPs ever related to recent times and genealogy? Are they always for historic periods and more ancient ancestry?
No. Y-Chromosome DNA SNPs (single nucleotide polymorphisms) are not always from anthropological or even [...]
The Y-Chromosome Consortium’s (YCC) has published a new version or update of their tree. [...]
The Y-Chromosome Consortium (YCC) updates their tree several times a year. There is usually [...]
Across the entire Y-Chromosome DNA, a SNP occurs every one to two generations.
In the Xue 2010 paper, [...]
Yes, the same SNP may appear in more than one haplogroup. This is because [...]
There are differences between the phylogenetic trees because there are differences in standards. Family [...]
The Advanced Order SNPs are SNPs (single nucleotide polymorphisms) from recent scientific research and other discoveries. They [...]
