Final answer:
False, a pedigree chart does not show relationships outside a family since it is used to depict inheritance patterns within a family to understand genetic traits and disorders.
Step-by-step explanation:
Pedigree charts are used to trace and predict the probability of inheriting genetic disorders or traits, and they utilize a set of symbols to signify gender, marriage, offspring, and the manifestation of specific traits over generations. Each horizontal row represents a generation, circles represent females, squares represent males, and a horizontal line connecting a circle and a square indicates a union with offspring depicted by vertical lines stemming from this connection. Furthermore, pedigree charts can indicate whether a trait is sex-linked or autosomal by studying inheritance patterns. They are a fundamental tool for scientists and genetic counselors in understanding the genetic risk factors within families. Kinship charts, however, can include a broader range of relationships including consanguineal (biological) and affinal (marital or agreement-based) relationships, potentially encapsulating more than just familial bonds. Kinship charts utilize different types of lines to indicate various relationships such as marriage, descent, and adoption.
