Current partner takes it to reproduce (7)
I believe the answer is:
imitate
'to reproduce' is the definition.
(imitating is a kind of reproducing)
'current partner takes it' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'partner' becomes 'mate' (synonyms).
'takes' indicates putting letters inside.
'mate' enclosing 'it' is 'mitate'.
'i'+'mitate'='IMITATE'
(Other definitions for imitate that I've seen before include "Copy (mannerisms)" , "Copy, simulate" , "Appear like, in behaviour or appearance" , "I ate Tim! (anag.)" , "I tame it (anag)" .)
