I believe the answer is:
pedigree
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">lineage</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(pedigree is a kind of lineage)</span><br/ ><br/ >'<span class="explanation-format__original">ancestry</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(pedigree is a kind of ancestry)</span><br/ ><br/ ></span>
(Other definitions for pedigree that I've seen before include "Line of decent or ancestry" , "Lineage of purebred animal" , "Of animals, recorded line of descent" , "List of ancestors" , "(Pure) ancestry" .)
