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’ x 2 1/2’ 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! Kit includes complete instructions with reproducible student handouts, valuable teacher notes, and detailed background information. Durable materials may be used year-after-year.
