Genograms are used to graphically display your medical
family history -- a kind of medical pedigree chart that contains special
symbols that indicate the sex and relationship of each family member.
Unlike a traditional pedigree chart, genograms do not require names,
birth and death dates, and they usually only cover three or four generations.
The standard set of symbols for a genogram are:
A circle indicates a female
A square indicates a male
An x through one of the above indicates the person
A horizontal solid line connecting two people shows
a committed (i.e., married) connection
A horizontal solid line which is slashed indicates
a divorce or non-committed relationship
A vertical or diagonal solid line indicates a biological
A vertical or diagonal dashed line indicates a special
relationship such as adoption
