Question

Homology is exhibited by:

• A. Wings of butterfly, birds, and bat
• B. Paddle of whale, forearm of horse, and forelimbs of man
• C. Tail of monkey and birds
• D. Sting of scorpion and Apis

Answer 1

The correct option is B

Paddle of whale, forearm of horse, and forelimbs of man

The correct option is B:

Explanation of the correct option:

1. Homologous organs are organs that have a similar structure but perform different functions in different animals.
2. Although the anatomical structure of the organ is similar the function differs.
3. The forelimbs of frogs, humans, and whale paddles are examples of homologous organs. All the structures are similar but they perform different functions.

Explanation of the incorrect options:

Option A:

The wings of butterflies, bats, and birds perform a similar function of flying but have different structures.

Option C:

The tail of monkey and birds have different structure and does not show homology.

Option D:

The sting of scorpion and Apis do not have a similar structure and therefore, do not show homology.

Final answer: Homology is exhibited by the paddle of a whale, the forearm of a horse, and the forelimbs of man.
