Q.Explain the mode of sex determination in honeybees.

Step 1. State the mechanism's name and scope: honeybees, along with ants and wasps (the hymenopteran insects), use a system called haplodiploidy, distinct from every sex-chromosome-based system covered earlier in the chapter.

Step 2. State the rule: the sex of the offspring is determined purely by how many sets of chromosomes it receives — fertilised eggs develop into diploid females (which can become either a queen or a worker depending on later developmental/nutritional factors), while unfertilised eggs develop into haploid males (drones) through parthenogenesis, development from an unfertilised egg without a second parent's genetic contribution. …

Explain haplodiploidy's fertilised/unfertilised rule as it applies specifically to honeybe …
