Here shows a genogram with pink and blue colour. A genogram is just a more advanced version of a family tree. To begin, you create a family tree that spans two or three generations (or more if you feel really ambitious). Rather than only collecting historical data about your family, you also keep track of patterns of behavior and the strength of connections among family members. Most young people appreciate the opportunity to talk about their family history, and it may be a useful tool for establishing trust and rapport in a professional setting.
