A pedigree chart is a tool used in genetics to trace the inheritance of a specific trait or disease within a family. It helps to visualize the relationships between family members and identify patterns of inheritance. Pedigree charts are typically used to study genetic disorders and can provide valuable information for genetic counseling and medical research.
When creating a pedigree chart, individuals are represented by symbols such as squares for males and circles for females. Relationships between individuals are shown with lines connecting the symbols, indicating parent-child relationships, siblings, and other family connections.

By practicing with these tests, you can improve your skills in pedigree chart analysis and gain confidence in interpreting genetic information.
Conclusion
