Волфганг Хаак ми изпрати лично неговото изследване, само настоява да не се публикува.
Аз му зададох въпроса защо при толкова много проби, при които е възможно голям брой да са с добре запазена ДНК, не се прави изследване за У хаплогрупи и той ми отговори това:

We will have Y-chromosome results one day, we're screening them as we speak but that's still a few months away from publication. You're right that with this large number of samples there must be some that are preserved well enough to allow Y-data generation. We attempted it a couple of times in the past, but a success rate of 10% on average is not a very economic use of time and resources. Plus, the amount of extract that's needed to generated a Y-SNP or Y-STR profile, which is well replicated and authentic stands in no relation to the amount of information it can provide. We there decided early on to save precious DNA extract and wait until we can generate nuclear SNP data (incl. Y) or even low X coverage genomes from the samples. That's what happening at the moment, so no need for conspiracy theories.

Т.е до няколко месеца можем да научим и резултати за Y хромозома. Очаква се и напредък в методите да се използва малко количество ДНК за аутозомни изследвания.
