Options

A.

C.
D.

Answer

To solve the question of which symbol is used for five unaffected offspring in a pedigree chart, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pedigree Symbols**: In a pedigree chart, different shapes represent different genders and conditions. Males are typically represented by squares, females by circles, and unspecified sex by diamonds.

2. **Identifying Unaffected Offspring**: The question specifically asks for "five unaffected offspring." This means we need to find a symbol that indicates offspring that are not affected by a particular trait or condition.

3. **Analyzing the Options**:
- If the option shows a square or circle, it would represent a male or female, respectively, not offspring in general.
- If the option shows a shaded shape, it would indicate that the offspring are affected, which is not what we want.
- The correct representation for unaffected offspring is a diamond shape that is not shaded.

4. **Representing Multiple Offspring**: To indicate multiple offspring, we can place a number inside the diamond shape. In this case, we need to represent "five unaffected offspring," so we would write the number "5" inside the diamond.

5. **Final Answer**: The symbol used for five unaffected offspring is a diamond shape with the number "5" inside it.
