Genetic Corn Kits & Sets
Why is corn an excellent choice for introducing students to Mendelian inheritance? To start with, Carolina does the
ears of corn, so you can literally do
an instant genetics lab. There are numerous contrasting phenotypes expressed in corn kernels (corn seed). These phenotypes are easy to recognize, and even beginners can score them with confidence.
• The large number of kernels on each corn ear from Carolina 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 lacquer-treated to improve appearance and increase durability.
Carolina BioKits® : Corn Dihybrid Genetics Cross over to better understanding
• Complete kit that introduces dihybrid inheritance • High-quality corn ears last for years • Reusable kit elements
With this kit, students learn the basic principles of dihy- brid inheritance and inde- pendent assortment using corn. Students first observe how traits of kernel color and nutrient composition pass from 1 generation to the next. Then they con- struct a hypothesis describ- ing the mode of inheritance for each trait. This kit is designed for 30 students working cooperatively in pairs. Kit includes:
15 Segregating Ears (Purple:Yellow Starchy:Sweet) 15 Corn Cross Cards 15 Transparency Markers Plastic Storage Container Teacher’s Manual and Reproducible Student Guide

“This is a very useful product—the corn provided a basis for a good lab on dihybrid crosses. I used the kit with an advanced biology class, it was easy to use, and the stu- dents learned a lot from the hands-on experience.”

Monohybrid Genetics
with Corn Kit Beginning—Easy to perform; requires little or no prior knowledge.
For up to 32 students working in pairs. This is an introductory genet- ics activity for a begin- ning high school or middle school biology course. Students study
the inheritance of grain color using ears of corn. Each grain is the F2 of a cross
between a homozygous red corn and a homozygous white corn. Covers the basics of Mendelian genetics including the inheritance of a single pair of alleles, one of which is dominant and the other recessive. Students score phenotypes of the F2 and compare their data to their predictions. Kit includes:
16 Segregating Ears (red:white or purple:yellow; based on availability) 3 Teacher Transparencies 32 Transparency Markers Storage Box

Mendelian Genetics of Corn Kit Learning more about genetics
Intermediate—Easy to perform; requires some background knowledge.
For up to 32 students working in groups of 4. Designed for advanced high school classes or
introductory college-level
classes, this genetics lab cov- ers all the basics of Mendelian genetics in 1 easy-to-use kit. Topics include segregation and the independent assort- ment of alleles, dominance, genotype and phenotype, expected ratios, monohybrid and dihybrid crosses, and chi-square. Kit includes:
