Reproduce type (5)
I believe the answer is:
breed
This clue is a double definition.
'reproduce' is the first definition.
(breeding is a kind of reproducing)
'type' is the second definition.
(thesaurus)
(Other definitions for breed that I've seen before include "Livestock classification" , "Produce children" , "Rear; variety" , "Special variety of domesticated animal" , "Mate specific animals to produce certain qualities" .)
