The given diagram shows the chromosomes of Drosophila melanogaster.The autosomal pairs are labelled as
Correct answer: C. I, II and III
- A. I and II
- B. III and IV
- C. I, II and III
- D. I, II and IV.
Explanation
In Drosophila melanogaster, the chromosomes are organized into distinct pairs. The first, second, and third pairs are autosomal chromosomes, while the fourth pair is the sex chromosomes. Therefore, the correct answer is Option D: I, II, and III Option A is incorrect as it excludes one autosomal pair. Option B is incorrect as it misidentifies the autosomes. Option C IS correct as includes the first, second and third pair as an autosome.
