R Color Alleles 3:1 • Shows relationship between genotypes and phenotypes
• Perfect for demonstrations
• May be used as a refill for Mendelian Genetics of Corn Kit (item #176360) and Monohybrid Genetics with Corn Kit (item #176362)
What’s the fastest way to explain the relation- ship between genotypes and phenotypes? Use this 1 ear of corn. Purple:Yellow. An F2 resulting from a P1 generation having the geno-
ear
types R/R and r/r. 176500 Per ear
Wx Endosperm Alleles 3:1 Starchy:Waxy. Demonstrates segregation of the recessive endosperm character, waxy. Iodine solution (item #177020) is used to distinguish the phenotypes.
176550 Per ear Corn Mounts
Corn mounts show diagrammatically the sequence of events that leads to the hybrid ear. Sections showing the phenotypes of each generation are presented and each genotype is printed below the specimen.
Monohybrid Cross
R and Su Alleles 9:3:3:1 Discovering dihybrids • Appropriate for teacher demos
• May be used as a refill for Mendelian Genetics of Corn Kit (item #176360)
• For studying dihybrid inheritance
With this corn ear, it’s easy to show your students inheritance patterns for organisms that differ in 2 traits. Purple Starchy:Purple Sweet:Yellow Starchy:Yellow Sweet. An F2 resulting from a P1 generation having the geno-
ear
types R/R Su/Su and r/r su/su. 176600 Per ear
