Which type of sex determination is seen in honey bees?
Options
- AZZ-ZW type
- BXX male - XY female type
- CHaplo-diploid type
- DXX female - XY male type
Correct answer
C. Haplo-diploid type
Step-by-step solution
Honey bees exhibit a haplo-diploid mechanism of sex determination. In this system, the sex of the offspring is determined by the number of sets of chromosomes it receives. Fertilized eggs develop into diploid females (queens or worker bees), which have 32 chromosomes. Unfertilized eggs develop into haploid males (drones) by parthenogenesis, which have 16 chromosomes. Therefore, the sex determination in honey bees is of the haplo-diploid type. Answer: Haplo-diploid type
