Q.What is haplodiploidy?

Step 1. Define the term: haplodiploidy is the mechanism of sex determination found in hymenopteran insects such as honeybees, ants and wasps, in which sex depends not on a pair of sex chromosomes at all, but on the number of chromosome sets an individual receives.

Step 2. State the rule: fertilised eggs develop into diploid females (queens or workers), while unfertilised eggs develop into haploid males (drones) by parthenogenesis — males therefore have half the chromosome number of females, which is where the name 'haplo-diploidy' comes from. …
