Though a bit lazy got every fertilized egg (6)
I believe the answer is:
zygote
'fertilized egg' is the definition.
(I've seen this in another clue)
'though a bit lazy got every' is the wordplay.
'ZYGOTE' is hidden within the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for zygote that I've seen before include "A fertilised ovum" , "Egg/sperm-union cell" , "Cell resulting from two gametes fusing" .)
