Indicate the type of isolating mechanism described in each scenario. a. habitat isolation b. temporal isolation c. behavioral isolation d. mechanical isolation e. gamete isolation f. zygote mortality g. hybrid sterility h. low $\mathrm{F}_{2}$ fitness Females of one species do not recognize the courtship behaviors of males of another species.
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

Which of these outcomes are examples of reproductive isolation? Select all that apply. Individuals of different species are physically compatible and can engage in sex Hybrid individuals cannot produce offspring Hybrid individuals or their offspring have similar fitness to the original species Reproduction occurs at different times Mating occurs but fertilization does not occur
