Step 1 Identify the Need or Problem Define Problem/Scenario: You need to design a model or simulation that will demonstrate how a trait can skip a generation. Expected Task: Create a model of how two different traits are passed from grandparents to parents to offspring. The model must be able to use all possible combinations of alleles represented by at least three sets of parents. Step 2 Research the Need or Problem Research and Citations: Vocabulary: Heredity, Genetics, Chromosomes, Genes, Alleles, Dominant, Recessive, Genotype, Phenotype, Punnett Square, Probability, Homozygous, Heterozygous Step 3 Develop Possible Solution(s) Criteria: Identify two traits that each have two separate alleles to be used in the model.
