Which of the following is important for speciation : -A new species forms when a population can no longer interbreed with its parent population.
Reproductive isolation (by any barrier, prezygotic or postzygotic) prevents gene flow between the populations, so they evolve independently and become separate species.
Seasonal and behavioural isolation are particular types of reproductive isolation.
So reproductive isolation is important for speciation.
