### Understanding Pedigree Charts in Genetics
Pedigree charts are visual representations of a family’s genetic history, showing how traits are passed down from generation to generation. These charts are commonly used in genetics research and genetic counseling to track the inheritance patterns of specific traits or diseases within a family. By analyzing a pedigree chart, geneticists can determine the likelihood of an individual inheriting a particular trait or disease.

Lines connecting individuals show familial relationships, with horizontal lines representing marriage and vertical lines representing offspring. By studying the patterns of inheritance in a pedigree chart, geneticists can better understand the genetic basis of certain traits and diseases.
