These two frog species separate by reduced hybrid viability. In reduced hybrid viability gene of different parent species may interact and impair the hybrid's development while in a reduced hybrid fertility a viable individual is sterile often due to the inability to produce normal gametes in meiosis. Hybrid breakdown; the first generation are viable and fertile, but when they mate the offspring are feeble and sterile.

This process is called as imprinting. It occurs at a particular stage of life and is, therefore, a phase-sensitive learning process. It can be of many types, including filial imprinting, where an offspring gains some of its behavioral characteristics from the parent, or sexual imprinting, through which desirable characteristics of a mate are recognized by a young animal.
