OMG! Honey could display similarity! (8)

I believe the answer is:

homogeny

I'm a little stuck... Click here to teach me more about this clue!

'similarity' is the definition.
(I know that homogeny is a type of similarity)

'omg honey could display' is the wordplay.
'omg honey' anagrams to 'HOMOGENY'.
Though, I'm not clear how the anagram is indicated.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
