I find myself still confused about the haplogroups assigned by FTDNA.
FTDNA says: "* Haplogroups in *green* have been confirmed by SNP
testing. Haplogroups in *red* have been predicted by Family Tree DNA
based on unambiguous results in the individual's personal page." and "we
see no reason for ordering a SNP test to confirm the Haplogroup".

However, it seems to me that, in respect of the sub-clades, the FTDNA
haplogroup tells us nothing. Take for example the three MEGONNIGIL
results at positions 205, 206, 207 in the R1b1c7 Project. Test numbers
17624 and 17860 are identical at 67 positions, and 17623 has one
difference in the haplotype at CDYb, a fast mutating position.

I take it that 17624, MEGONNIGIL jnr is the son of one of the other two.
Now 624 is M222+ tested, and shown in green as R1b1c7. The other two are
shown as R1b1 and presumably untested. If one is the father, by
definition he will be M222+. Why is he not so shown?

Further, does this imply that any member shown in red as R1b1 might, in
fact, be M222+? In that case, the FTDNA statement above is more or less
meaningless, is it not?
