Related but mutated? (7)
I believe the answer is:
altered
'mutated?' is the definition.
(mutating is a kind of altering)
'related' is the wordplay.
'related' anagrams to 'ALTERED'.
Though, I am not clear how this is indicated.
'but' is the link.
Can you help me to learn more?
(Other definitions for altered that I've seen before include "Metamorphosed" , "Converted" , "Change" , "Reformed" , "Different" .)
