Which of the following correctly pairs a prezygotic reproductive barrier with its description or example, as presented in Figure 24.3?

  • A: Habitat Isolation: Western and eastern spotted skunks breed at different times.
  • B: Temporal Isolation: Blue-footed boobies require a unique courtship display before mating.
  • C: Behavioral Isolation: Apple and blueberry maggot flies feed and mate on different host plants.
  • D: Mechanical Isolation: Snails with oppositely spiraled shells cannot align their genital openings.

Explanation

The example of snails with oppositely spiraled shells g directly illustrates mechanical isolation, where morphological differences prevent successful completion of mating. Option A describes temporal isolation, option B describes behavioral isolation, and option C describes habitat isolation.
