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: Written information by the students about the need or problem being solved with citations noted. 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. (eye color is one trait that has a brown allele and a blue allele). Determine which train it dominant and which is recessive. The model must be able to predict the possible outcomes of different parents (not just one set of parents). Materials should be used to physically distribute items that represent alleles. Display how a trait can skip a generation. Constraints: Only select traits that display complete dominance. Materials: Many small objects of varied colors such as marbles, coins, etc. and paper bags or cups Step 4 Select the Best Possible Solution(s)/ Step 5 Construct a Prototype Building of the Product (Prototype, model or Artifact): Teams must come up with clears rules for separating alleles within individual parents and combining alleles from different parents. Each group must create a technical diagram which shows how their model works. Step 6 Test and Evaluate the Solution(s) Testing of the Product (Prototype, model or Artifact): When testing the model, each team should record the genotype (allele pairs) and phenotypes (appearance of trait) “input” of each grandparent and then the “output” which are the genotypes and phenotypes of the possible offspring. The teams should calculate the probability that the offspring will have a particular trait and provide the code to interpret the data. .
