Question

Haplodiploidy is a mechanism of sex determination that is common in

• A. Cockroach
• B. Birds
• C. Bugs
• D. Wasps

Hint:

Haplodiploidy is unique to certain species, including wasps, ants, and bees, where the sex of the offspring is determined by the number of chromosome sets inherited.

Answer 1

The Correct Option is D

Haplodiploidy as a Sex Determination Mechanism

Haplodiploidy is a sex determination mechanism where the sex of the offspring is determined by the number of sets of chromosomes they inherit.

• Cockroach: In cockroaches, sex determination follows the XX/XY system, not haplodiploidy. Incorrect.
• Birds: Birds also use the ZZ/ZW system for sex determination, which is different from haplodiploidy. Incorrect.
• Bugs: Many bugs, like cockroaches, also follow the XX/XY sex determination system, so they don't typically use haplodiploidy. Incorrect.
• Wasps: In wasps, haplodiploidy is a common mechanism where unfertilized eggs become males (haploid) and fertilized eggs become females (diploid). Correct.

Conclusion: The correct answer is Option D, which refers to Wasps.
