Pls answer fast
In bees,
After copulation between queen and the drone,the haploid drone inseminates his sperm inside the body of the queen,then what is the ploidy number of the sperm?
Answers
In honeybees, the drones (males) are entirely derived from the queen, their mother. The diploid queen has 32 chromosomes and the haploid drones have 16 chromosomes. Drones produce sperm cells that contain their entire genome, so the sperm are all genetically identical except for mutations.

Heya !!!
Here's the answer !!
➡In Hymenopteran insects (honey bees , ants and wasps) ,the mechanism of sex determination is Haplodiploidy.
➡The sex of the organism is determined by the number of sets of chromosomes it receives.
➡A Queen bee(fertile female) is diploid and the drone (fertile male)is haploid.
➡In Apis mellifera (European bee) , drones are haploid with 16 chromosomes , Queen and worker bees are diploid with 32 chromosomes.
➡Drones and Queen are fertile whereas the worker bees are sterile females.
➡Queen(diploid) is developed from fertilized egg and is fed with royal jelly , worker bees(diploid) are also developed from fertilized eggs but are fed with honey and pollen whereas the drones(haploid) are developed from unfertilized eggs
➡The Queen produces gametes by meiosis in which each gamete (ovum)receives 16 chromosomes and the drone produces gametes by mitosis in which each gamete(sperm) receives 16 chromosomes.
Since, your question is about the ploidy of the sperm ....
The Sperm (male gametes) are HAPLOID as they are produced by mitosis in haploid drones...
Hope this helps you :)
