<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">genetic copies</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for clones that I've seen before include "Propagates as with Dolly the sheep" , "Genetically identical copies" , "Genetically identical organisms derived from a single cell" , "Identical copies of cells" , "Organisms reproduced asexually" .)
