Produces current character unit assessments (9)
I believe the answer is:
generates
'produces' is the definition.
(generating is a kind of producing)
'current character unit assessments' is the wordplay.
I cannot really understand how this works, but
'character' could be 'rat' (I have seen 'Unpleasant character' mean 'rat' so perhaps 'character' could also mean 'rat') and 'rat' is located in the answer.
'unit' could be 'gene' (I have seen 'Unit of heredity' mean 'gene' so perhaps 'unit' could also mean 'gene') and 'gene' is located in the answer.
The remaining letters 'es' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
