Which one of those is my haplogroup?

[Ekaitza]

I put my DNA data at morleydna.com and it gave me 3 different haplogroups:
- R1b1a2: R1b-L265 (R1b-M269, R1b-M520)
- R1b1: R1b-L506 (R1b-L278, R1b-M415)
- K: K-PF5504 (K-PF5493, K-PF5480)
How I determine which one of those is my haplogroup?

Which one was your most likely one?

Morley is only a tool, you're likely R1b but I wouldn't base your specific subclade off a predictor tool, you'd need a y-dna test for that.

The first. Which is the best test for determine this?

FTDNA. Y-37 would be enough.
