Explanation:
In the given information of edible frog both male and female hybrids exist, but when they mate among themselves, they cannot successfully produce offspring which defines that postzygotic isolation exists between the two frog species
- Postzygotic isolation prevents the formation of fertile offspring
- Before the postzygotic isolation can happen, there must be an offspring born from a male and female of two different species
- This means there were no prezygotic isolations, such as the fitting together of the sex organs or incompatibility of the gametes or differences in mating rituals or locations, that kept the species in reproductive isolation
- The offspring of two different species known as a hybrid is not always viable
