A Pedigree Chart Biology is a genetic representation of a family tree that depicts the inheritance of a trait or disease over multiple generations. The pedigree shows the relationships between family members and indicates which individuals express or silently carry the trait under consideration. This Pedigree Chart Biology also depicts the investigation of a specific trait passed down from generation to generation. It is useful to understand the trait of inheritance for a particular trait and whether or not the trait is inherited. Pedigrees are family trees that show the parents and offspring of each generation and who possess specific characteristics. Genetic counselors use individual family pedigrees to help them provide information to families who may be interested.
