Here you can seeSantos Genogram. A genogram has a structure similar to a family tree, yet it serves an entirely different purpose. A genogram includes information about family relationships and interactions, whereas a family tree merely shows lineage. A genogram, as we all know, is a diagram depicting a person's family members, their relationships, and their medical history. The genogram enables the patient to see inherited behavioral patterns, as well as medical and psychological issues that run in families.
