    Y-dna Survey of your 23andme matches

    It occurred to me that 23andme customers could use their ~1000 matches as somewhat random polling data to get an idea of the percentage of y-dna (or m-dna) in this rather US centric database. In other words you could get an idea of the make up of y-dna or mitochondrial dna in the US

    For example assuming half the matches are male:

    -Of my approx. 553 male matches 194 (35%) are R1b-P312, 65 are R1b-U152 (12%) and 40 (7.2%) are R1b-L2

    -Of my mother's approx 533 male matches 165 (31%) are P312, 37 are U152 (7%), and 20 (3.7%) are L2

    -Of my father's approx 505 male matches 188 (37%) are P312, 52 (10%) are U152, and 31 (6.1%) are L2.


    In this small sample of kits it appears P312 makes up ~35% of 23andme's database, while U152 is ~28% of P312, and L2 is ~58% of U152.
    More samples would give you a higher confidence and if you had enough participants you could get a pretty good idea of the actual 23andme database percentages.

    An example of how this could be used in the forums would be a member starting a new thread in say the L21 section asking 23andme customers to post their percentage of L21 matches.

    I tried this a little while ago (although i didn't go into as much detail as you have), and the matches seem to broadly reflect the composition of a person's ancestral background, and judging from the results people from other countries got, it appeared to be different for them.

    I might do it again but in more detail to look at the ratios of different R1b groups as you have done, would be interesting.

    I did that as well for my results of the general y dna and mitochondrial dna....there was a thread asking folks to post their results. As you said, this idea would be further down the tree in detail.
