The sex determination in honey bee is based on the number of sets of chromosomes an individual receives. An offspring formed from the union of a sperm and an egg develops as a female (queen or worker), and an unfertilised egg develops as a male (drone) by means of parthenogenesis. This means that the males have half the number of chromosomes than that of a female. The females are diploid having 32 chromosomes and males are haploid, i.e., having 16 chromosomes. This is called as haplodiploid sex-determination system and has special characteristic features such as the males produce sperms by mitosis.

Chromosome difference in honey bees
Honey bees have a unique sex determination system where females are diploid (having two sets of chromosomes) and males are haploid (having one set of chromosomes). This is different from most other organisms where males are typically the heterogametic sex.
Explanation of option C
The statement in option C is incorrect because all workers and males in honey bee colonies have 16 chromosomes, while the queen bee has 32 chromosomes. This difference in chromosome number is due to the process of haplodiploidy in honey bees.
Haplodiploidy in honey bees
In honey bees, fertilized eggs (resulting from the union of sperm and egg) develop into females (queens and workers) with two sets of chromosomes, while unfertilized eggs develop into males by means of parthenogenesis. Therefore, all females in a honey bee colony have 32 chromosomes, while males have 16 chromosomes.
Function of chromosomes in honey bees
The difference in chromosome number between males and females in honey bees plays a crucial role in their social structure and behavior. The haplodiploid sex determination system in honey bees is associated with the development of reproductive castes (queens and drones) and non-reproductive workers in the colony.
In conclusion, the statement in option C regarding chromosome number in honey bees is incorrect. It is important to understand the unique sex determination system in honey bees to appreciate their complex social organization and behavior.
