The type of sex determination in honeybees is

The mechanism of sex determination in honeybees is haplodiploidy. The sex of the individual is determined by the number of sets of the chromosomes they have. Males are produced from unfertilised eggs and have only one set of chromosomes (haploid), while females are produced from fertilised eggs and have two sets of chromosomes (diploid). The haplodiploidy mechanism of sex determination is unique to certain insect species such as honeybees, wasps and ants; it is not found in other animals, including humans. It is thought to have evolved as a way to efficiently produce males, which are typically smaller and have fewer developmental requirements than females. The haplodiploidy mechanism also has implications for social behaviour and kin selection in these species.
