Description

Lab-Aids Investigating & 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. Punnett squares are used to predict the ratio of phenotypes that will be produced by different crosses, and students will analyze the actual ratio of phenotypes of the second generation offspring. A reading describes traditional selective breeding and modern genetic engineering approaches to improving crops. This kit is complete for 32 students and is reusable. Includes a Teacher’s Guide, 32 Student Worksheets & Guides - Part 1 & 2, 32 Reading: Breeding Crops with Desirable traits, 2 “Breeding Corn: First Generation” transparencies, 2 “Breeding Corn: Second Generation” color transparencies, 16 Corn “Ear A”, 16 Corn “Ear B”, 16 Corn “Ear C”, and 16 Corn “Ear D”.
