The reproductive isolating mechanism in which two closely related species live in the same geographic area but reproduce at different times is (a) temporal isolation (b) behavioral isolation (c) mechanical isolation (d) gametic isolation (e) hybrid inviability
Reproductive isolation is a. a result of individuals not mating with each other. b. a specific type of postzygotic isolating mechanism. c. $\quad$ required by the biological species concept. d. $\quad$ None of the choices is correct.
Reproductive isolation: Match the type of isolation with its definition. Gamete Isolation Mechanical Isolation Temporal Isolation Ecological Isolation A. Size or organ compatibility prevent mating B. Sperm and egg do not attract each other or properly fuse C. Species occupy different niches, therefore rarely interact D. Reproduction occurs at different times of day or year
