What is the pedigree symbol for a diseased male?

In pedigree charts, symbols are used to represent individuals and their traits, particularly for genetic conditions. The specific symbol for a diseased male is a filled-in square. The square represents a male, and when it is filled in, it indicates that the individual expresses the trait or disorder being studied, which in this case is a genetic disease.

The other symbols have distinct meanings as well. An empty square indicates a healthy male, while an empty circle represents a healthy female. A filled-in circle represents a diseased female. Each symbol provides clear visual cues to help understand the inheritance patterns of conditions across generations. By using these established symbols, healthcare providers and genetic counselors can easily interpret pedigrees to assess risk and inheritance of genetic disorders.
