Honeybees produce their young ones only by sexual reproduction. Inspite of this, in a colony of bees we find both haploid and diploid individual. Name the haploid and diploid individual in the colony and analyse the reasons behind their formation.

Solution

In a beehive only queen bee and drones have fully developed reproductive organs. When queen bee mates with a drone, the genital organs of drone are reversed and a part will be left inside queen bee after ejaculation of the spermatozoon, and drone dies. In similar manner queen bee mates with 8-12 drones and stores spermatozoa in her spermatheca. During laying eggs queen bee chooses whether to fertilize every egg that passes through her oviduct. So unfertilized eggs become haploid male bees and fertilized eggs become diploid female bees.
