Which of the following options correctly represents the properties of queen, drone and worker in a beehive?

Options

A. Queen - diploid fertile female, Drone- haploid fertile male, Worker- diploid sterile female
B. Queen-haploid fertile female, Drone-haploid fertile male, Worker- diploid sterile female
C. Queen-diploid sterile female, Drone-haploid sterile male, Worker- diploid fertile female
D. Queen-haploid fertile female, Drone-haploid fertile male, Worker-haploid sterile female

Answer

To solve the question regarding the properties of queen, drone, and worker bees in a beehive, we will analyze the characteristics of each type of bee based on their reproductive roles and genetic makeup.

### Step-by-Step Solution:

1. **Understanding the Queen Bee:**
- The queen bee is diploid, meaning she has two sets of chromosomes (2n).
- She is fertile and capable of producing eggs through meiosis, which results in haploid gametes (n).
- The queen is the only reproductive female in the hive.

**Hint:** Remember that the queen is the primary reproductive individual in the hive.

2. **Understanding the Drone Bee:**
- Drones are haploid, meaning they have only one set of chromosomes (n).
- They develop from unfertilized eggs through a process called parthenogenesis, which is a form of asexual reproduction.
- Drones are male and are not capable of producing offspring without fertilization.

**Hint:** Drones are produced without fertilization and are haploid.

3. **Understanding the Worker Bee:**
- Worker bees are also diploid (2n) but are sterile females.
- They develop from fertilized eggs, but their diet during the larval stage determines their role. If they receive less royal jelly, they become workers.
- Workers perform all the tasks in the hive except reproduction.

**Hint:** Workers are diploid but do not reproduce; their role is to support the hive.

4. **Evaluating the Options:**
- **Option A:** Queen is diploid and fertile female. (Correct)
- **Option B:** Drone is haploid and fertile male. (Correct)
- **Option C:** Worker is diploid and sterile female. (Correct)

Since all three statements accurately describe the properties of the queen, drone, and worker bees, the correct answer is that all options are appropriate.

### Conclusion:
The correct representation of the properties of queen, drone, and worker in a beehive is that the queen is a diploid fertile female, the drone is a haploid fertile male, and the worker is a diploid sterile female. Therefore, the answer is **A**.
