A Genogram of Jadie Family Tree shows here. A genogram resembles a family tree in structure, yet it serves a totally different purpose. A genogram contains information about family relationships and interactions, whereas a family tree merely shows lineage. The genogram, as we all know, is a common method for determining who is in the family and what role essential family members play in relation to one another. The traditional genogram comprises biological family members; however, genograms can also include individuals who serve a specific function within the family.
