In humans, the allele for having dimples is dominant to the allele for not having dimples. what would you expect to see in the offspring of a woman with dimples who is homozygous and a man who is heterozygous for the trait?
answer
all of their offspring will have dimples.
none of their offspring will have dimples.
the probability of their offspring having dimples is 50%.
their offspring will have a 75% chance of having dimples.

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.
