Resemble (4,5)
I believe the answer is:
take after
'resemble' is the definition.
(I know that take after is a kind of resemble)
This is the entire clue.
(Other definitions for take after that I've seen before include "Resemble, follow in the footsteps of - say a parent" , "Look or be like, say parent" , "Resemble or imitate someone, often parent" , "Resemble as offspring may parent" , "Favour" .)
