Genetics: Mendelian Concepts Simulation
This activity allows students to collect data that show similar patterns to those Mendel discovered. Using specially designed equipment, students “rediscover” the principles of genetics. The unique materials produce random genotype combinations that are statistically consistent with those found when studying living organisms.

Scientific Concepts
•Traits are influenced by alleles located on chromosomes.
•Each organism has sets of paired alleles (genotype) that help determine its physical traits (phenotype.)
•Alleles come in two versions (often represented with upper- and lower-case letters) and genotypes can be homozygous (e.g. XX or xx) or heterozygous (e.g. Xx).
•Each offspring gets one allele randomly from each parent.
KEY VOCABULARY: Alleles, Chromosomes, Deoxyribose nucleic acid (DNA), Dihybrid, Dominant, Genotype, Incomplete dominance, Inherited, Phenotype, Recessive

Kit #77Heredity
By germinating hybrid tobacco seeds first in darkness and then in light, students make interesting observations using this challenging kit. Students set up controlled experiments that provide mathematical data to test their theoretical genetic hypothesis about heredity and the factors determined by the environment. They see how a recessive trait becomes evident. Students also...

Kit #71DNA Model
The two activities in this kit introduce students to the structure of the DNA molecule and how its structure allows it to replicate. Using a unique Lab-Aids modeling set, students first build an 8-rung DNA double helix and learn the base-pairing rule. Then starting with a 4-rung segment, they unzip the ladder and create...

Kit #607SModeling Protein Structure & Its Relationship to Traits
This kit introduces the concept that a gene encodes for a protein with a specific structure and function in the cell and that protein function manifests as observable traits. In Part 1, students build physical models as they explore how a geneís DNA sequence codes for a protein sequence and how the protein...

Kit #912SModeling the Inheritance of Traits
Students model the diversity of offspring possible from two parents and discover patterns of inheritance other than strict dominant/recessive traits. These patterns help them model and explain the wide variation that can result from sexual reproduction and explore the cause-and-effect relationships for additional traits of the critters.

Kit #603SInvestigating and Applying Genetics
Students build their understanding of selective breeding for desired traits in crops such as corn. They investigate the outcomes of crosses of hybrid and dihybrid corn plants for two unlinked genetic traits: corn kernel color and sweetness. They use Punnett squares to predict the ratio of phenotypes that will be produced by different crosses...
