I believe that one, affinities are not inheritable. Two, I do not believe that the pup will even rebel or like his/her parents. Three, no, if I am correct.
I /do/ believe -however- that the affinity is all based on the affinity with your pack. If a wolfs affinity with you is excellent, I think that his/her affinity with the other wolves would be decent too. But then again, I might be wrong. :)
