Answer 1

Step 1: Understanding the Concept:
Sex is determined by the number of sets of chromosomes.

Step 2: Detailed Explanation:
1. Female (Queen/Worker) = Diploid (2n = 32).
2. Male (Drone) = Haploid (n = 16).
3. Fertilized egg (32) → Female.
4. Unfertilized egg (16) → Male (Parthenogenesis).

Step 3: Final Answer:
Queen (2n = 32) → Meiosis → Egg (n = 16).
Egg + Sperm (n = 16) → Female (2n = 32).
Egg → Parthenogenesis → Male (n = 16).
