### Pedigree Analysis

#### Overview of Diagram:

The image depicts a pedigree chart illustrating two families, Family 1 and Family 2. The chart traces the inheritance of a specific trait, highlighted by shading. The squares represent males, and the circles represent females. The shaded figures indicate individuals who express the trait, while unshaded figures represent individuals who do not express the trait.

#### Family 1:

- **Generation 1**: 
  - One shaded circle (female)
  - One unshaded square (male)
- **Generation 2**: 
  - Two unshaded squares (males)
  - One unshaded circle (female)
  - One shaded circle (female)

#### Family 2:

- **Generation 1**:
  - One shaded square (male)
  - One unshaded circle (female)
- **Generation 2**:
  - One unshaded circle (female)
  - One shaded square (male)
- **Generation 3**:
  - One unshaded square (male)
  - One shaded circle (female)
  - One shaded square (male)
  - One unshaded square (male)

#### Questions:

1. **How many generations are in this pedigree?**
   - There are three generations depicted in the pedigree.

2. **What sex is the youngest child in generation 2 of family 1?**
   - The youngest child in generation 2 of Family 1 is a female (circle).

3. **Is the shaded trait dominant or recessive? Circle the area that shows the answer.**
   - The chart does not provide explicit information about whether the trait is dominant or recessive. However, generally, if a trait manifests in every generation, it may suggest a dominant inheritance pattern, especially if it appears in both males and females. Further analysis is needed for confirmation.

4. **What is the normal trait for the family?**
   - The normal trait for the family, represented by the unshaded figures, is the lack of the shaded trait.

This diagram serves as a tool to understand the inheritance patterns of genetic traits in families, demonstrating how traits pass from one generation to the next.
