## Pedigree Chart Analysis

The image contains a pedigree chart used to track the inheritance of a specific trait through several generations in a family.

### Explanation of the Pedigree Chart

The pedigree consists of four generations, labeled with Roman numerals I to IV on the left-hand side. 

**Legend:**
- Squares represent males.
- Circles represent females.
- Filled shapes indicate individuals expressing the trait.
- Half-filled shapes indicate carriers of the trait (heterozygous individuals).
- Blank shapes indicate individuals not expressing the trait, nor carriers.

### Generations

**Generation I:**
- Individual 1: Male, carrier of the trait (half-filled square).
- Individual 2: Female, does not express the trait (blank circle).

**Generation II:**
- Individual 1: Female, does not express the trait (blank circle).
- Individual 2: Male, expresses the trait (filled square).
- Individual 3: Female, carrier of the trait (half-filled circle).
- Individual 4: Male, does not express the trait (blank square).

**Generation III:**
- Individual 1: Male, does not express the trait (blank square).
- Individual 2: Female, expresses the trait (filled circle).
- Individual 3: Male, carrier of the trait (half-filled square).
- Individual 4: Female, does not express the trait (blank circle).
- Individual 5: Female, does not express the trait (blank circle).

**Generation IV:**
- Individual 1: Male, expresses the trait (filled square).
- Individual 2: Female, does not express the trait (blank circle).
- Individual 3: Male, expresses the trait (filled square).

### Question and Opportunities

Below the pedigree chart, a multiple-choice question is presented, with the question indicated by a black circle:
- Select the correct probability regarding a given trait.
  - 1/2
  - 3/8 (selected)
  - 1/8
  - 1/16
  - 1/4

This pedigree chart helps in understanding the mode of inheritance of a certain genetic trait within a family, which can be crucial for genetic counseling, risk assessment, and understanding hereditary patterns.
