Which of the following forms of reproductive isolation are pre-zygotic...

II. Gametic Isolation: Gametic isolation occurs when the gametes (sperm and egg) of different species are unable to fuse or undergo successful fertilization. This can be due to differences in gamete structure, biochemistry, or other mechanisms that prevent successful fertilization.

IV. Temporal Isolation: Temporal isolation occurs when two species have different mating times or breeding seasons, preventing them from coming into contact and mating with each other.
