A pedigree chart is a diagram that shows the genetic relationships within a family. It is commonly used in biology to track the inheritance of genetic traits over multiple generations. Each individual in the chart is represented by a symbol, with lines connecting them to show their relationships. Pedigree charts are a valuable tool for geneticists and researchers to analyze patterns of inheritance and identify genetic disorders within families.
Interpreting a pedigree chart requires an understanding of the symbols and patterns used in the diagram. Squares represent males, circles represent females, and shaded symbols indicate individuals with a particular trait or disorder. Lines connecting the symbols show relationships such as parentage and siblings. By analyzing the patterns of inheritance in a pedigree chart, researchers can determine whether a trait is dominant or recessive, and predict the likelihood of passing that trait on to future generations.
