Three species of sea stars all mate near the same reef by secreting their gametes into the water, but none of the gametes from the different species fertilize each other. this is an example of a barrier called

Answer;

-Prezygotic; gametic isolation

This is an example of a prezygotic barrier called gametic isolation.

Explanation;

-Prezygotic barriers are those barriers that prevents mating and fertilization is a prezygotic mechanism. Habitat isolation, behavioral isolation, temporal isolation, mechanical isolation and gametic isolation are all examples of prezygotic isolating mechanisms.

-Gametic isolation is a mechanism of reproductive isolation which inhibits mating between two distinct species, by ensuring that their gametes don't interact with each other. This incompatibility of gametes prevents the formation of inter-species hybrids, and maintains the integrity of the species.
