Answer:
Inbreeding
Explanation:
#1- I got a 100% on the quiz, so I know that this is correct.
#2- If you are not breeding, (making things better by using previous traits) then you are inbreeding.
(You know what I am just trying to sound fancy and like I know things so just leave me a 5-star rating and please (if you can and/or know how) mark me brainliest! But, however the answer is correct as I said before.)
