Explanation

Haploid-diploid mechanism or Haplodiploidy is a unique phenomenon in which an unfertilised egg develop into a male and a fertilised egg develops into a female. Therefore, the female is diploid (2n), and the male is haploid (n), Eggs are formed by meiosis and sperms by mitosis. Fertilisation restores the diploid number of chromosomes in zygote which gives rise to the female. If the egg is not fertilized, it will still develop but into a male (arrhenotoky or arrhenotokous parthenogensis). It is seen in hymenopterous insects, such as beeds, wasps, saw flies and ants.
