Selective breeding is the process of breeding plants or animals so that they inherit particular traits from their parents. Which of these is not possible with selectively breeding a crop species?

the dark variety, as they are not visible on the dark tree barks

explanation:

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
