Pedigree charts are a simple way for geneticists to see how people in a family are related to one another. A geneticist interviews a member of a family and asks about her/his relatives. A set of standard symbols are used - circles for females, squares for males, a diagonal slash to indicate someone who is dead, and so on. Lines link people who are related (except for parents who have a line joining them but are nevertheless not related). http:// www.sc2000.net/~czaremba/labs/pedigree.html http://esg- www.mit.edu:8001/esgbio/mg/pedigrees.html http:// www.biology.arizona.edu/human_bio/problem_sets/human_genetics/05t.htm
