1) are ancestry dna tests(mtDNA,Y-chromosome STR test) reliable?
2) in the case of Y-chromosome test,as long as they analyse markers on the Y chromosome,does it give ancestry only on the father of my father of my father.... or on the whole of my father's side(and his father,mother,etc.) If it gives ancestry on both sides,is it due to some gene swapping occurring at mitosis,meiosis?
3) in the case of mtDNA test,does it reflect only my mother's side?,or again both due to gene swapping as before?
4)is it then ancestry tests on autosomal markers the most reliable?
5)are the different R1b(or I,R1a,etc.) types(a,b,c..) something real or just invented to fake differences by country?
