Hi Folks,

A question for genealogical experts. Lets say that a person has 14-15 tested positive SNPs under Paternal Haplogroup F and 1-3 positive under Haplogroup H. Where would he be placed in, H or F?

The ones tested positive/negative under H are as follows :

My raw data file from Genographic/FTDNA showed that I was :

Positive for M69
Negative for M52
Negative for APT
and Surprisingly
Positive for P-80
and Positive for P266

Now the question as per the FTDNA/Geongrpahic Y haplotree is : how could somebody be positive for P80 and P266 at the same time and not positive for APT?

I am pasting a screen shot of the haplotree below to show the phylogeny.

23and me put me in F instead of H!

What's the status of H SNPs further upstream?

(BTW, the latest ISOGG page says "P266 as listed in Karafet et al. 2008 has incorrect mutation information and is withdrawn until correct information is available.")

There are non above M 69. H starts from there :

Newer haplotrees have a couple of levels above (prior to) M69 but still within haplogroup H. Here is YFull's haplotree for H (https://yfull.com/tree/H/).

Too many changes and different haplotrees, addition , substraction of SNPS, moving them from here n there. A very evolving tree and not an exact science then. I guess the haplotree is very young and in the developmental stages. It covers only a fraction of population may be even less than 1 % of the population and hence all the ambiguities/uncertainties.

Why is it they think M69 and PAGES00049 are false positives?? I understand the other two are likely false positives.

The science is exact but not static. Yes, our knowledge is continually growing.

I am not talking about the science that says one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom ( this is absolute) or that the formula of Nitrogen di oxide is NO2 ( exact)

I am talking about the YDNA tree here. The Y DNA tree has lots of errors and poorly structured under certain haplogroups and incorrectly placed SNPS. The Tree is based on a few sample populations ( perhaps less than 1 percent of the different ethnic groups are covered ) and hence not an exact science !

Hope you understand what I meant! The current knowledge in this field is meager and incomplete.

That is why everybody needs to do Full Y chromosome sequencing (if they can spare the bucks)
