Genogram for Markus family therapy topic 7 is shown here. The genogram is a popular way of determining who belongs in a family and what role essential family members play in relation to one another. A genogram resembles a family tree in structure, but it serves a very different purpose. A genogram contains information about family relationships and interactions, whereas a family tree merely shows lineage. A genogram surpasses the conventional family tree because it is an in-depth schematic diagram that depicts the relationships, hereditary and behavioral patterns shared by members of a family, and how these patterns impact the lives of the family members.
