Match List I with List II
Choose the correct answer from the options given below:
| List I (Types of isolating mechanisms.) | List II (Reason) |
|---|---|
| (A). Habitat isolation | (I). Difference in the structure of reproductive organs |
| (B). Temporal isolation | (II). Occupies different habitats and do not mate |
| (C). Ethological isolation | (III). Mature sexually at different times |
| (D). Mechanical isolation | (IV). Specific mating behavoiur of members |
Options
- A(A) - (I), (B) - (II), (C) - (III), (D) - (IV)
- B(A) - (II), (B) - (IV), (C) - (I), (D) - (III)
- C(A) - (I), (B) - (II), (C) - (IV), (D) - (III)
- D(A) - (II), (B) - (III), (C) - (IV), (D) - (I)
Correct answer
D. (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
Step-by-step solution
Habitat isolation occurs when two species occupy different habitats within the same area and thus rarely encounter each other to mate. Therefore, (A) matches (II).
Temporal isolation occurs when species breed or mature sexually at different times, such as different times of the day, different seasons, or different years. Therefore, (B) matches (III).
Ethological (behavioral) isolation is due to specific mating behaviors or courtship rituals that are unique to a species, preventing members of different species from mating. Therefore, (C) matches (IV).
Mechanical isolation happens when morphological differences, such as differences in the structure of reproductive organs, prevent successful mating. Therefore, (D) matches (I).
The correct matching is (A) - (II), (B) - (III), (C) - (IV), (D) - (I).
Answer: (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
