Given below are two statements. One is labelled Assertion (A) and the other is labelled Reason (R).

Assertion (A): In a honeybee colony, the drones do not have a father and thus cannot have sons, but have a grandfather and can have grandsons.

Reason (R) : Drones are diploid while the queen is haploid in the colony.

In light of the above statements, choose the correct answer from the options given below.

(A) is true but (R) is false.

Assertion (A) correctly states a unique aspect of honeybee reproduction. Drones do not have fathers, as they develop from unfertilised eggs laid by the queen bee. Therefore, they cannot have sons. However, they do have a grandfather (the queen's mate) and can have grandsons through their potential offspring produced by a queen.

Reason (R) is false. Drones are haploid, while the queen bee is diploid. This is because drones develop from unfertilised eggs, while workers and queens develop from fertilised eggs.
