In "Nine Wives," Millie and Charlie examine a quilt found during an investigation. Millie shows Charlie that the quilt is actually a family tree for Abner Stone's cult. Because this cult is a small group that practices polygamy, it is quite possible that the same person can be both the paternal and maternal grandfather of a person who has unrelated grandmothers. This activity examines the genetic implications of this situation.
