Sperm of a starfish cannot penetrate the coat of the egg of a similar starfish species with overlapping ranges. The barrier keeping these species separate is: A. the postzygotic barrier called hybrid breakdown B. the prezygotic barrier called gametic incompatibility C. the prezygotic barrier called temporal isolation D. the postzygotic barrier called hybrid sterility
