I had a discussion with a person who knows how to extract Y dna data from samples. He said that the Chinese theytree service is not as reliable as Yfull. They upload too much low coverage samples. So caution is needed with their results. It will be a good practice to double check their results with FTDNA service if the sample is available there also.
If You notice a discrepancies between FTDNA and the Chinese theytree results please report here. Especially if they pertain to ancient Armenian samples.
In any case this do not affect my yesterday's thread because Lazaridis also says that there was at last one M269 positive but negative to L23 which is equal to PF7562. The number I14057.
