Honey Bees have a much different social and reproductive structure as compared to humans.
djyliett [7]

Answer:

Unlike the queen bee, which has 32 chromosomes, drones have half the chromosomal charge (n= 16), so they are considered haploid.

Explanation:

The system of determination of the sex in the bees —like in other insects— is called haplodiploidy, and consists of which the females of the species possess complete charge of chromosomes, whereas the males only possess half. This is what happens with the queen bee with 32 chromosomes, while drones only have 16 chromosomes, so they are considered haploid.

Additionally, as a characteristic of haplodiploidy, males only proceed from female gametes, so they can only contribute gametes to produce females of the species.

The other options are not correct because:

  • <em>Drones, with half of the chromosomal charge, </em><u><em>cannot be diploid</em></u><em>. </em>
  • <u><em>Monosomy and trisomy</em></u><em> are defects in the distribution of chromosomes during meiosis, which imply one chromosome less or one chromosome more in the normal chromosome charge respectively.</em>
