Which of these is an example of behavioral isolation?

a.) the frog species rana aurora breeds in fast–moving streams, whereas its relative rana catesbiana breeds in still ponds.

b.) two species of pines, pinus radiata and pinus muricata, grow together in california, but pinus radiata sheds its pollen in early february and pinus muricata in april.

c.) two species of crickets, gryllus rubens and gryllus texensis, have different courtship songs which can be identified only by the opposite sex of their own species.

“Two species of crickets, Gryllus rubens and Gryllus texensis, have different courtship songs which can be identified only by the opposite sex of their own species” is an example of behavioral isolation.

Behavioral isolation is an important evolutionary mechanism that helps members of the same species identify each other as proper mates.

The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

C.) Two species of crickets, Gryllus rubens and Gryllus texensis, have different courtship songs which can be identified only by the opposite sex of their own species.

Explanation:

The behavioural isolation can be define as the reproductive isolation which occurs when the two related species of the same species exhibit different mating rituals and signals which prevents them to breed with the two distinct populations.

C. is the correct option this is because of the fact that these two species utilize different courtship songs which can be used to attract the mates of opposite sex. This is likely to bring behavioral isolation between the two species of crickets.

the sun d the answer is sun

the denominator has a very specific role.
