This article concerns the relations between the probability generating functions of the controlled branching process with random control function. By derivation of the probability generating functions, the conditional or unconditional expectation and variance of the process are obtained. These relations and moments generalize some basic results of the process in terms of the probability generating functions, expectation and variance.
