Likeness or similarity (11)
I believe the answer is:
resemblance
I believe this clue is a double definition.
'likeness' is the first definition.
(I know that resemblance is a type of likeness)
'similarity' is the second definition.
(I know that resemblance is a type of similitude)
(Other definitions for resemblance that I've seen before include "Likeness" , "Similar image" , "Similarity of appearance" .)
