Study Notes
Pre-Zygotic Isolating Mechanisms
-
Habitat Isolation
- Species occupy different habitats within the same geographical area.
- Reduced likelihood of encountering and mating due to spatial separation.
-
Temporal Isolation
- Related species can coexist in the same environment but have different reproductive times.
- Varying mating seasons or times of day prevent interbreeding.
-
Behavioral Isolation
- Unique courtship rituals and patterns facilitate species recognition.
- Specific behaviors must align for successful attraction and mating between species.
-
Mechanical Isolation
- Reproductive structures are physically incompatible.
- Structural differences in genitalia of animals or floral structures of plants hinder fertilization.
-
Gamete Isolation
- Even if gametes from two species come into contact, fusion may not occur.
- Chemical or structural incompatibilities prevent the formation of a zygote.
