Question

Which of the following is a premating isolating mechanism?

Options

• Gamete isolation

• Habitat isolation

• Temporal isolation

• Both Habitat isolation and Temporal isolation

Answer 1

Both Habitat isolation and Temporal isolation

Explanation:

Premating isolating mechanisms prevent mating or fertilization between species. Habitat isolation occurs when species live in different environments, and temporal isolation occurs when species breed at different times. Both are examples of premating barriers, while gamete isolation happens after mating but before fertilization.
