Genuine in path one’s taken (6)
I believe the answer is:
honest
'genuine' is the definition.
('honest' is associated in meaning with 'genuine')
'in path one's taken' is the wordplay.
'in' indicates a hidden word.
'HONEST' is hidden within 'path ones taken'.
(Other definitions for honest that I've seen before include "Not cheating, just" , "Direct" , "Sincere, upright" , "Honourable, true" , "Not dissembling" .)
