Sanitation elevated hereditary factor in report (7)
I believe the answer is:
hygiene
'sanitation' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for hygiene that I've seen before include "Clean, healthy habits" , "Cleanliness, sanitation" , "Clean and healthy practices" , "Healthy cleanliness" , "Practice of cleanliness to maintain health" .)
