<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">identical copy</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for clone that I've seen before include "Copied organism" , "Identical copy" , "Organism reproduced asexually from one ancestor, like Dolly the sheep" , "Not an original individual" , "Person who is identical to another" .)
