pedigree charts
A pedigree chart is a visual tool used to trace the inheritance of a specific trait or genetic condition through generations of a family. It typically uses symbols like squares for males and circles for females, connected by lines to show relationships. By analyzing the chart, one can determine how traits are passed, identify carriers, and assess genetic risks. Pedigree charts are widely used by healthcare professionals to help understand family health history and guide medical decisions related to genetics.
