This is a 2 round panel that pinpoints the terminal SNP below G2a1-Z6552. This panel is suggested when you have tested Z6552+ or if you have a clear prediction for this haplogroup according to your Y-STR results.

In the first round 2 important SNPs will be tested to find out the main category:
FGC715
FGC750

In the second round the testing splits up depending on the results from round 1:
1.) If FGC715-, FGC750-
P15

Z31464
Z35447
Z31465
Z35443
