Question

What is the haplodiploid sex determination system?

Hint:

Haplodiploidy: Unfertilized eggs = males (haploid), fertilized eggs = females (diploid).

Answer 1

Haplodiploid Sex Determination System: In this system, sex is determined by the number of chromosome sets. Males develop from unfertilized eggs (haploid), while females develop from fertilized eggs (diploid).

The haplodiploid system is observed in honeybees and ants. In this system:

• Males (drones): Haploid (n) and arise from unfertilized eggs.
• Females (workers and queens): Diploid (2n) and develop from fertilized eggs.
