Why is it important that egg and sperm only have on set of chromosomes?

Egg and sperm cells contain only one copy of each chromosome pair. In the case of the sex chromosomes, sperm cells contain either the X or the Y chromosome

Explanation:

answer; i believe that the correct answer is (light);

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.
