he inheritance pattern of traits such as PTC tasting can be diagrammed in a chart lled a pedigree. A pedigree illustrates the marriages for several generations thin a family and the children produced. Females are shown with circles and males are shown with squares. A black square or circle shows the presence of the condition being studied. A white square or circle means the condition is absent in that person. A marriage or mating is shown by a line connecting the parents. Children from a mating are shown by a vertical line between the parents. All individuals from the same generation are shown along the same horizontal line. After examining the pedigree key, determine the genotypes of all the people in this family. In a few cases, there may not be enough information to determine a person's second allele. In this situation, enter a question mark (?) in place of the second letter. John Joan Pauline Keith
