please i need a help
1-for the family tree dna ,If i had Y-DNA test of 12 markers ,could they tell me that my haplogroup is J only as for instance or they will determine if iam J1 or J2? I mean is Y-DNA 12 markers enough to determine if iam J1 or J2?
2- can 25 markers Y-DNA test determine if you are J1e or J1b as an examples or not?if not so what is the useful of 12 ,37,42,67 markers tests?
