Q38 (NDA-I/2016) Science & Technology › Basic Science (Physics, Chemistry, Biology) › Genetics and evolution Answer Verified

Which of the following statements are correct ? In honey bees . 1. Males are haploid. 2. Workers are sterile and diploid. 3. Queen develops from diploid larvae that fed on royal jelly. 4. Honey is collected/made by males. Select the correct answer using the code given below :

Result
Your answer: —  Â·  Correct: C
Explanation

Honey bee colonies exhibit a haplodiploid sex-determination system. Males (drones) are haploid, developing from unfertilized eggs. Females, including both workers and queens, are diploid, developing from fertilized eggs. Worker bees are sterile females that perform all colony maintenance tasks, including foraging and honey production. The queen is the only reproductive female; she develops from a diploid larva that is exclusively fed royal jelly, a nutrient-rich substance secreted by worker bees. While workers collect nectar and process it into honey, drones do not participate in foraging or honey production; their primary role is mating with a virgin queen. Therefore, statements 1, 2, and 3 are correct, while statement 4 is incorrect because honey is made by female workers, not males.
