A pedigree chart is a visual representation of a person’s ancestry, showing relationships and genetic traits across multiple generations. These charts are commonly used in genetic counseling, genealogy research, and biology classes to track inherited traits within a family.
When answering pedigree chart test questions, it’s important to understand how to interpret the symbols and relationships depicted in the chart. Common symbols include squares for males, circles for females, and lines connecting individuals to indicate parent-child relationships.
