Introduction:
Honey bees have a unique sex determination mechanism known as haplodiploidy. Unlike mammals, where sex is determined by the presence of sex chromosomes, in honey bees, sex is determined by the number of chromosomes.
Explanation:
The correct sex determination pattern in honey bees is as follows:
Male:
- Male honey bees, also called drones, are haploid, meaning they have half the number of chromosomes compared to other bees.
- Drones are produced from unfertilized eggs, which contain only one set of chromosomes.
- Therefore, the correct chromosome number for male honey bees is 16.
Female:
- Female honey bees, including both workers and queens, are diploid, meaning they have the full complement of chromosomes.
- Female honey bees are produced from fertilized eggs, which contain two sets of chromosomes.
- Therefore, the correct chromosome number for female honey bees is 32.
Analysis of given options:
a) Male 32, Female 16: This combination is incorrect because it swaps the chromosome numbers for males and females. It suggests that females have a haploid number of chromosomes (16) and males have a diploid number (32).
b) Male 16, Female 32: This combination is correct. It aligns with the haplodiploid sex determination pattern in honey bees, where males have a haploid number of chromosomes (16) and females have a diploid number (32).
c) Male 31, Female 32: This combination is incorrect. It suggests that males have a near-diploid number of chromosomes (31) and females have a diploid number (32), which does not align with the haplodiploid sex determination pattern in honey bees.
d) Female 32, Male 31: This combination is incorrect because it swaps the chromosome numbers for males and females. It suggests that males have a diploid number of chromosomes (32) and females have a near-diploid number (31).
Conclusion:
The correct sex determination pattern in honey bees is that males have a haploid number of chromosomes (16) and females have a diploid number (32). Therefore, option B (Male 16, Female 32) represents the correct sex determination pattern in honey bees.

Conclusion:
The correct sex determination pattern in honey bees is that males have a haploid number of chromosomes (16) and females have a diploid number (32). Therefore, option B (Male 16, Female 32) represents the correct sex determination pattern in honey bees.
