Pedigree analysis is the study and analysis of the inheritance pattern of a particular trait in several generations of a family. It helps to understand the pattern of inheritance for a particular trait. It also helps in knowing the possibilities of prospective parents transmitting heritable disorders to their children. It is widely used in genetic counselling and medical research.

The diagramatical representation of the inheritance pattern of a particular trait in a family for several generations is known as the pedigree chart.

Sex unspecified means sex of the person is not mentioned.
