Autosomal Y-dna på familytreedna

[Renate Hagen]

Familytreedna har annonsert at de vil gi alle genetiske menn med en family finder test en Y-dna haplogruppe. Dette gjelder alle som har tatt en test med familytreedna, eller har overført en test fra f.eks MyHeritage eller Ancestry. Autosomal mtDNA vil bli annonsert neste år.

«This means you’ll only receive a partial haplogroup from an autosomal test. Most customers can expect this haplogroup to have originated in the Metal Age (about 10,000 years ago). Comparatively, a predicted, broad haplogroup from a Y-STR test like the Y-37 or Y-111 will typically have originated in the Stone Age (about 100,000 years ago), and a haplogroup from the Big Y-700 will typically have originated in the Middle Ages or in the Modern Age (about 1,000 to 500 years ago)—within genealogical times.»

«23andMe and National Geographic's Geno 2.0 test are primarily autosomal DNA tests, but they will also report your paternal line and maternal line haplogroups.

 

23andMe and Geno 2.0 do not report yDNA haplotype information or the mtDNA differences most useful for genealogy. Y haplotypes are revealed by Y-DNA37 or Y-DNA67 tests (12, 24, 37, 67 or 111 Short Tandom Repeat (STR) markers). mtDNA differences are shown as Hyper Variable Region (HVR) differences from the RSRS or rCRS.

 

The haplogroups reported by 23andMe and Geno 2.0 began thousands of years ago. They identify the broad branches of human ancestry. They may be useful for rejecting a genealogical connection but they are not useful for confirming one.

For example, if two men are in different haplogroups we can be certain that they have different fathers. However, if two men are in the same haplogroup we cannot be certain that they have the same father. Far from it. Millions of men are in the same haplogroup. On the other hand, if their haplotype is a close match we can confirm that they share a common paternal ancestor in a genealogical time frame.»
