Question:

The sex determination in honey bee is based on the number of sets of chromosomes an individual receives. So, the males are _____ having _____.

Options:

Haploid, 32 chromosomes

Diploid, 16 chromosomes

Haploid, 16 chromosomes

Diploid, 32 chromosomes

Correct Answer:

Haploid, 16 chromosomes

Explanation:

The correct answer is Option (3) → Haploid, 16 chromosomes

The sex determination in honey bee is based on the number of sets of chromosomes an individual receives. An offspring formed from the union of a sperm and an egg develops as a female (queen or worker), and an unfertilised egg develops as a male (drone) by means of parthenogenesis. This means that the males have half the number of chromosomes than that of a female. The females are diploid having 32 chromosomes and males are haploid, i.e., having 16 chromosomes. This is called as haplodiploid sex-determination system and has special characteristic features such as the males produce sperms by mitosis, they do not have father and thus cannot have sons, but have a grandfather and can have grandsons.
