    RE that danged 519

    I'm often lumped with another group for convenience, and it irks me.

    My HVR1: 270 & 519
    Other group HVR1: 270 all by itself.

    That makes the ancestral origins page, etc., less elucidating.

    Actually, if you go back through this chain of ancestors, you should be able to figure out the ancestral version of most markers:

    Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.

    thank you for your answer, cacio

    but what about 519C? what is different with that ...

    and another question: what exactly is a snp?

    Apart from 16519, these are not mutations. As you say, the are the ancestral values.

    The results only say that you differ from CRS in those SNPs, but they don't say who has the original values and who has the mutation. In this case, it is CRS who has a mutation, and you have the original values.

    As for when CRS had these mutations, they must be pretty recent, perhaps a few thousand years, because these are found only in the sub-branch where CRS is.

    mutations - ancestral version

    hello,

    519C, 263G, 309.1C, 309.2C, 315.1C
    many times are said to be the "ancestral version" of a haplotype.
    my question: how old are these mutations?

    best regards
    mrh
