Answer:
prezygotic ... behavioral isolation
Explanation:
Prezygotic barrier is a reproductive barrier that occurs when fertilization is prevented from occurring as a result of isolation leading to prevention of copulation, and as such there is no fusion of gametes for fertilization to take place, and eventually formation of zygote. Zygote is not formed as fertilization does not take place.
Behavioral isolation is a prezygotic reproductive barrier that prevents two or more different species to copulate together in order for fertilization to take place due to differences in behavior that is unique to each species. One of such behaviors is mating calls.
As a result of the differences in mating calls which is unique to each species of frogs mentioned in the question, only members of each species get attracted to themselves and mate with their members, thereby making it almost impossible for the three different species of frogs to mate together.
I hope this helps A gene is a segment of DNA containing the code used to synthesize a protein. A chromosome contains hundreds to thousands of genes. Every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait<span> is any gene-determined characteristic and is often determined by more than one gene.</span>

CELL REPRODUCTON: many organelles are involved in cell reproduction, including the nucleus and the mitochondria and chloroplasts. All of these organelles contain DNA that must be replicated so that each new cell will have complete copies.
The role of stomata in photosynthesis is often undervalued. But, these tiny pores control the entrance of carbon dioxide and the exit of oxygen and water vapor.
