What is the term for the reproductive isolating factor that occurs when there is an incompatibility between a sperm and an egg?

Reproductive isolation is the inability of two different species to interbreed and produce fertile offspring. Gametic isolation is a type of prezygotic barrier that results from an incompatibility between the sperm of one species and the egg of another species. This incompatibility can be due to differences in the proteins or other molecules on the surface of the gametes, preventing them from recognizing and fusing with each other. Therefore, the best option that characterizes a reproductive isolating factor that results from an incompatibility between a sperm and an egg is gametic isolation.

Ecological isolation refers to reproductive isolation that results from differences in habitat or other ecological factors. Behavioral isolation refers to reproductive isolation that results from differences in mating behavior, such as differences in courtship rituals or pheromone signals. Temporal isolation refers to reproductive isolation that results from differences in the timing of reproductive activities between two species. other.
