A pedigree chart is a diagram that shows the genetic relationships between individuals in a family. It is commonly used in genetics to track the inheritance of traits and diseases. By analyzing a pedigree chart, one can trace the patterns of inheritance within a family and predict the likelihood of certain traits or diseases being passed on to future generations.
When completing a pedigree chart worksheet, it is important to understand the symbols and conventions used in the chart. Typically, squares represent males, circles represent females, and shaded symbols indicate individuals with the particular trait or disease being studied. Arrows may be used to indicate the proband, or the person from whom the pedigree is initiated.
