Imitated, aped (6)
I believe the answer is:
copied
I believe this clue is a double definition.
'imitated' is the first definition.
('copy' can be a synonym of 'imitate')
'aped' is the second definition.
('copy' can be a synonym of 'ape')
(Other definitions for copied that I've seen before include "Reproduced (something)" , "made a transcript" , "Imitated or recreated" , "most sincerely flattered" , "Imitated or replicated" .)
