Which of the following symbol is used for five unaffected offspring ?

Options

A.
B.
C.
D.

Answer

To solve the question of which symbol represents five unaffected offspring, we can follow these steps:

### Step 1: Understand the Symbols
- In genetic diagrams, males are typically represented by squares, while females are represented by circles.
- Shaded shapes indicate affected individuals, while unshaded shapes indicate unaffected individuals.

### Step 2: Analyze the Options
- The question provides five symbols, and we need to identify which one represents five unaffected offspring.
- We need to look for a symbol that does not show shading (indicating they are unaffected) and represents a group of five.

### Step 3: Evaluate Each Option
1. **First Option**: A square with the number 5. This indicates 5 unaffected males.
2. **Second Option**: A circle with the number 5. This indicates 5 unaffected females.
3. **Third Option**: A symbol indicating mating between relatives. This does not pertain to offspring.
4. **Fourth Option**: A symbol that shows five offspring without specifying gender. This indicates 5 unaffected offspring regardless of whether they are male or female.

### Step 4: Identify the Correct Answer
- The fourth option is the one that represents five unaffected offspring without specifying their gender. Therefore, the answer is **D**.

### Final Answer
The symbol used for five unaffected offspring is **D**.
