Question

Which is related to reproductive isolation?
A. Genetic isolation.
B. Behavioral isolation.
C. Temporal isolation.
D. All the above.

Answer 1

Hint: Reproductive isolation is characterized by when two fertile members of the same species are not involved in the mating process which is necessary for the reproduction. Reproductive isolation is also called a pre zygotic isolation process that means no zygote is formed.

Complete answer:
The premating isolation mechanism is called reproductive isolation. Which is classified in a number of ways, basically reproductive isolation is divided into two main broad categories, named as pre zygotic which is before mating and post zygotic which is after mating.
A. Genetic Isolation:- it is characterized by when two individuals carry different characteristics or features which do not allow them to mate and if they mate then they produce sterile offspring which act as barriers and show genetic isolation.
B. Behavioral isolation:- It is a type of reproductive isolation in which different animals follow different mating rituals, which create a strong reproductive barrier that is termed as sexual or behavior isolation, which can isolate the same species. Example In dioecious species, female and male parts are found in different plants so same species and they have to follow different mating practices to copulate or release their gametes into the environment.
C. Temporal isolation:- It is the type of prezygotic isolation which is also known as habitat isolation, which is characterized by when different habitat or environmental conditions create different maturation time periods for individuals that create strong physical barriers for reproduction.

So, the correct option is D.

Note: The reproductive isolation is created by evolutionary mechanisms, behaviors and physiological processes that are crucial for speciation, this will create barriers to prevent the different species from mating or producing offspring, to ensure the integrity of species.
