As students help construct and then analyze a pedigree chart of England’s Queen Victoria, they learn about sex-linked traits and the genetic patterns associated with sex-linked inheritance. This 5' × 2½' large-scale magnetic chart is easily assembled on any magnetic classroom board. Individual magnetic circles and squares may be rearranged so students can make their own pedigree charts—a great hands-on activity! Includes detailed instructions and reproducible student worksheet. Durable materials may be used year-after-year.
Concepts: Pedigree analysis, genetic probability, sex-linked trait. Time Required: One class period Materials Provided: Magnetic circles, magnetic squares, magnetic strips.
