Maybe you need to break it down into Ichigo's physical body and his soul?

1. Humans and Quincy both are born into mortal bodies with traits inherited from their biological mothers and fathers, while Shinigami and Hollows only exist as souls.

2. Fullbringers are Humans whose biological mothers were attacked by Hollows and in the process were forced to absorb part of those Hollows' powers. As a result the powers passed on to their children.

3. Since their physiology allow Humans to reproduce with Quincy (mixed blood), then maybe Quincy are Humans with a gene mutation; giving them special powers?

4. So based on that: Physiologically Ichigo is Human, with the Quincy gene mutation, while his soul has absorbed both Shinigami powers from Isshin and Hollow powers from Masaki.

(Btw. Did I just compare Quincy to X-men? O.o - That would make Ichigo=Wolverine and Yhwach=Magneto ^^)
