    How good/informative is the Y-DNA/mtDNA test offered by 23andme?

    The site only says that they test for "Maternal & Paternal Haplogroups", but there's no word on the scope of the test. They have a thanksgiving offer going right now and $69 sounds very tempting considering that other services charge hundreds for it, but is there a reason for the difference in price?

    It's exactly as they say - they only report the haplogroups. There are no Y/mt matches or other details. It's not really a Y/mtDNA test, it's an autosomal DNA test and they include enough Y/mtDNA data to report the haplogroups but that's it. The reason other services charge hundreds for Y/mtDNA tests is because you're getting much more from them.

    Mind telling me what else I'd be getting elsewhere and what you'd recommend?

    FamilyTreeDNA is the go-to for Y/mtDNA. The main benefit is the matches, which tend to be more useful for Y than mtDNA. I'd only recommend getting them done if you have a specific question or issue on the direct Y or mtDNA lines.

    I've read somewhere that the MyHeritage raw dna data actually contains the info regarding the Y-dna/mtDNA but MH just doesn't include this info in their report. Is there any known way to extract this information?

    Likewise, you’d only be able to get the haplogroups from that. It’s probably included in the raw DNA file download - Promethease.com and WeGene will provide haplogroups from the uploaded raw data. But unless I’m mistaken, MyHeritage only includes Y DNA, not mtDNA. Ancestry’s V1 chip included some Y data, not mtDNA, but their V2 chip includes both. These will likely not be the most specific subclade since the data included is limited.

    There was a thread where someone posted the myHeritage results of a relative and the Y-DNA coverage wasn't very good.

    Promethease isn't free and WeGene doesn't support MyHeritage raw data, but you say I'd only be able to get the haplogroups from that as if that info is insignificant. Do you believe that?

    23andme recently updated paternal haplogroups. Mine went from I-L22 to I-L205.1. I then requested an L205 test from FTDNA. It came back false. I asked Family Tree to double check and they promptly triple checked and confirmed their result. I requested a check from 23andme and haven't heard back yet. It makes me wonder how rigorous 23andme is for YDNA haplogroup testing.
    Known origins (6 generations): 48% south and east England, 25% Bothnian Sweden, 13% Ulster/Scotland, 5% Switzerland/Palatinate Germany, 9% Unknown

    23andme (50% conf.): 33% British&Irish, 23% Sweden, 17% French&German, 1.3% Finnish, 1% East European

    Eurogenes K36: 21% North Sea, 16% Fennoscandian, 13% Iberian, 12% N. Atlantic, 9% Italian, 8% Cent. Euro., 7% French, 5% E. Cent. Euro., 3% E. Euro., 6% Volga-Ural, W. Med., Basque, E. Med.

    I didn't say Promethease was free? And you didn't mention free... it's only $10 I think. And as mentioned, MyHeritage's Y data is very limited, only 482 SNPs versus 23andMe's 3,000+ and AncestryDNA's 1,000+.

    Haplogroups aren't relevant to recent genealogy. If you happen to get a subclade that is specific to a certain area, that can help pinpoint where that particular line came from, but that's not typical in my experience, and unlikely when the data is limited and may not provide the most specific subclade to begin with. Typically, haplogroups are from thousands and thousands of years ago and cover very broad areas of the world or continent. It's interesting, but not very useful.
