Carolina Teacher Tips - Kernels of Truth The large number of kernels on each corn ear gives a close approximation of the theoretical ratio Seed are still in their natural unit, for a convincing demonstration of Mendelian genetics The big visual difference in phenotypes makes recognition and seed-counting easy Ears are laquer-treated to improve appearance and hold seed firmly to the cob Each ear is fumigated, bagged, and labeled Corn is an excellent choice for introducing students to Mendelian inheritance. Carolina does the crosses and supplies F2 ears of corn so you can literally do an instant genetics lab. There are numerous contrasting phenotypes expressed in corn kernels (corn seed). The phenotypes Carolina typically uses involve the color or shape of the kernel. Our phenotypes are easy to recognize, and even beginners can score them with confidence!

• Shows relationship between genotypes and phenotypes
• Perfect for demonstrations
• May be used as a refill for Genetics of Corn Kit (#176360) and Monohybrid Genetics with Corn Kit (#176362)

What's the fastest way to explain the relationship between genotypes and phenotypes? Use this one ear of corn!

Purple:Yellow. An F₂ ear resulting from a P₁ having the genotypes R/R and r/r.
