Step one in creating a pedigree is to include only family members who have a blood relation. This means no step relations will be included. Next symbols for biological parents and siblings are added to the chart. Next, symbols for half siblings are added. Children are added next. The chart concludes with all members who have been diagnosed with a familial disease, with their ages designated in parentheses.
