In biology, a pedigree chart is a diagram that shows the genetic relationships within a family. It is commonly used to track the inheritance of genetic traits or diseases. The B5 pedigree chart is a specific chart that is labeled with different symbols and lines to represent individuals and their relationships. Understanding how to read and interpret this chart is essential for answering questions related to genetics and heredity on exams.
Each symbol on the pedigree chart represents a different individual in the family, with different shapes indicating gender and specific markings representing traits or conditions. The lines connecting the symbols show the relationships between family members, such as parents, siblings, and offspring. By analyzing the patterns in the chart, one can determine how traits are passed down from generation to generation.
