A pedigree chart is a visual representation of a person’s family tree, showing information about their ancestors and descendants. It is a valuable tool for geneticists and genealogists to track patterns of inheritance and genetic traits within a family.

When creating a pedigree chart, each family member is represented by a symbol, such as a square for males, a circle for females, and different colors or patterns to indicate specific traits or conditions.
