Question

Assertion (A): In hymenopteran insects, sperms are produced by mitosis.
Reason (R): Male hymenopteran insects are haploid.

• A. Both (A) and (R) are true, (R) is the correct explanation of (A)
• B. Both (A) and (R) are true, (R) is not the correct explanation of (A)
• C. (A) is true, but (R) is false
• D. (A) is false, but (R) is true

Hint:

Hymenoptera sex determination = haplodiploidy: males haploid (from unfertilised eggs), females diploid (from fertilised eggs).

Answer 1

The Correct Option is A

• Male hymenopterans (e.g., honeybee drones) are haploid — they develop from unfertilised eggs (arrhenotoky).
• In haploid males, spermatogenesis proceeds by mitotic divisions (there is no meiosis because cells are already haploid) — so A is true and R explains it.
• Therefore the correct choice is (1).
