His Hollow powers come from his mother because she was bitten and infected with Hollowfication by White, so Ichigo inherited both of the Zangetsu's from her as one represents his Quincy powers, and the other his Hollow powers, his Shinigami side comes from his father which is his base power, so to sum it up essentially his weapons come from his mother and his Shinigami body from his father.
