Which one of the following statements is true for most ants and bees?

Question

A patient is suffering from the infection of the alveoli of lungs and is showing the symptoms of fever, chills, cough, headache, and bluish-colored lips and fingernails. The patient was diagnosed to be suffering from the infection of:

Answer 1

This question checks whether you remember how sex is fixed in ants and bees through haplodiploidy, and which combination of ploidy (haploid or diploid) and egg type (fertilised or unfertilised) goes with which sex.

Males are diploid and develop from fertilised eggs: wrong on both counts. In haplodiploid insects, males carry only one chromosome set (haploid), and they hatch from eggs the queen never mated to fertilise.
Males are haploid and develop from fertilised eggs: half right. Males really are haploid, but that single chromosome set comes from an unfertilised egg, since fertilisation is exactly what would add the second set and make them diploid.
Females are diploid and develop from fertilised eggs: this is the correct pairing. Sperm from a male adds a second chromosome set to the egg, making the resulting female diploid, whether she becomes a worker or a queen.
Females are diploid and develop from unfertilised eggs: the ploidy is right, females are diploid, but the egg type is wrong. Without fertilisation there is only one chromosome set, which gives a haploid male, not a diploid female.

So the statement that holds up on both the ploidy and the egg type is that females are diploid and come from fertilised eggs, while males are haploid and come from unfertilised eggs, a process called arrhenotoky.

Let's summarize:

Fertilised egg, two chromosome sets, diploid female.
Unfertilised egg, one chromosome set, haploid male.

The correct statement is that females are diploid and develop from fertilised eggs.
