उत्तर
In the honeybee, the haplodiploid sex-determination system determines the sex of the offspring. In this system, sex is determined by the number of sets of chromosomes an individual receives. An offspring developed from fertilized egg develops as a female and unfertilized egg develops in males. A female offspring shows diploid (2n = 32) number of chromosomes. Males (drones) produced by means of parthenogenesis have haploid (n = 16) number of chromosomes
