Gee, I'd go for it, sounds promising. :)
Palestinian dad is not cooperative.
Answer from 23&me
Thank you for contacting the 23andMe Team. The analysis performed is the same for men and women, and both men and women receive ancestry information based on DNA they receive from both parents.
For each pair of your chromosomes, one comes from your mother and the other from your father. These 22 autosomes are what we use to determine your DNA Relatives matches and your Ancestry Composition results, among other features.
The only piece of information that the 23andMe Personal Genome Service does not directly provide for women is the paternal haplogroup assignment. This is because the paternal haplogroup is traced through the Y chromosome, which women do not inherit.
Haplogroups are one small part of your ancestry analysis. You could potentially infer this information from your Ancestry Composition results if you see a significant portion that is either Middle Eastern or Southern European/Balkan (Greek). This would allow you to at least infer who your father could potentially be if you do not wish to have him tested.
Why is it that you don't want your Palestinian dad to know about this, does he not know there is a question? Post back when you hear from the 23andme people, I would be interested to hear if two areas as close together as Greece and Palestine (in other words, not next door to each other but not halfway around the world either) can be differentiated. I kind of think they could, simply because culturally they are so different that I would think there was not a ton of inter-marriage.
Thanks Annie
I should have also mentioned that maternal side is all Irish and British, so that should not confuse things
I have only seen the results of one 23andme test, and can't remember if it differentiated so closely as Palestine and Greece. It was very interesting, though. Certainly you could contact them and ask.
