A pedigree chart is a visual representation of a family’s genetic history. It shows how traits are passed down through generations and can help identify patterns of inheritance. Understanding pedigree charts is crucial for genetic counselors, medical professionals, and individuals interested in their family history.

A typical pedigree chart is shaped like a family tree, with squares representing males and circles representing females. Lines connect parents to their offspring, showing relationships and patterns of inheritance. Different symbols are used to indicate specific traits or conditions, such as circles filled with color for individuals with a genetic disorder.
