With this kit, students will: First study 2 monohybrid crosses in corn, and use Punnett squares to diagram the crosses and make predictions about the F2 resulting from each cross. They score phenotypes, compare their data to expected results, and draw conclusions. Building on their results, students are then asked to consider a cross that combines the 2 sets of alleles involved in the monohybrid crosses (i.e., a dihybrid cross). Students again construct a Punnett square to predict the F2 and collect data to test their predictions and draw conclusions.

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!

Intermediate - Easy to perform; requires some background knowledge.

• Complete Genetics Lab
• Comprehensive approach to teaching Mendelian genetics
• Materials are reusable and easy to store in supplied box

For up to 32 students working in groups of 4. This is a complete genetics lab for advanced high school classes or introductory college-level classes.

It covers the basics of mendelian genetics, including segregation and independent assortment of alleles, dominance, genotype and phenotype, expected ratios, monohybrid and dihybrid crosses, and chi-square.
