Question:
Which of the following sets do not have homologous organs?
Mouth parts of cockroach and butterfly
Wings of butterfly and bird
Wings of mosquito and butterfly
Forelegs of horse and paddles of whale
Solution:
Correct option is B. Wings of butterfly and bird. Wings of butterflies and birds are not homologous organs, they are analogous organs. It is because they are similar in function i.e., flying but different in their origin and structure. In contrast, homologous organs are similar in their origin and structure but have different functions. So, the correct answer is option B.
