Question:
In haplodiploidy
In haplodiploidy
Show Hint
Haplodiploidy: male = haploid (n), female = diploid (2n).
Updated On: Jul 18, 2026
- Sex of the offspring is determined by the number of sets of chromosomes
- Fertilized eggs develop into males
- Unfertilized eggs develop into females
- Females are haploid and males are diploid

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding haplodiploidy.
Haplodiploidy is a sex-determination system found in insects like honeybees and ants. It depends on chromosome number rather than sex chromosomes.
Step 2: Haploid and diploid condition.
Males develop from haploid eggs (n) while females develop from diploid eggs (2n). This difference determines sex of offspring.
Step 3: Fertilization role.
Fertilized eggs become diploid females, while unfertilized eggs become haploid males in haplodiploid organisms.
Step 4: Evaluation of options.
Options 2, 3, and 4 are incorrect because they reverse or misstate haploid and diploid conditions.
Step 5: Key principle.
The key factor is chromosome set number, not fertilization alone. This determines sex differentiation.
Step 6: Final conclusion.
Thus, sex is determined by number of chromosome sets in haplodiploidy.
