J. K. Rowling's Harry Potter series offer richly described characters whose appearances can serve as examples of how parents pass their genes with specific genetic traits to their children. Harry has the same bright green eyes that his mother, Lily, is described with. The Weasley family is known for their red hair and freckles. Draco Malfoy seems to have inherited the almost white blond hair and gray eyes in his father, Lucius. Hagrid is a son produced by a human and a giantess and his size is somewhere between a normal wizard and a giant. These Harry Potter characters provide a way for students to explore and apply basic concepts in genetics to the fictional characters that the students may already know much about by having read the series or watched the movies.
