What is the phenotype of a person whith the genotype I^Ai?

Type A

Explanation:

Mode of inheritance for blood is tricky, but type A and B are codominant, while type A and type B are dominant over O. So in this situtation

I^Ai is A because type a is dominant over o

easy

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.
