Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.
Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.
This activity guides the user through BioLogica's representations of chromosomes, genes, and alleles and stresses the connection between genotype and phenotype.
Students will be able to:
Politicians say that all politics is local. Biologists say that all traits are genetic. How would you explain that sentence to a politician?
This model-based activity is the introduction to a series of models with which students explore patterns of inheritance using dragons as the test animal. As they change allele combinations, they can follow changes in an organism. In this way, the relationship between genotype (the genetic makeup of the organism) and phenotype (the physical appearance of the organism) is reinforced for the student.
This model then opens the window for other activities focused on patterns of inheritance that use the BioLogica (dragons) model. You might choose from among these, including the following activities: Meiosis: Activity #86, Monohybrid: Activity #34, Xlinkage: Activity #143, and a complete three-week module BioLogica: Activity #30.
Genotype determines phenotype. Definition of traits, genotype, phenotype, chromosomes, genes, and alleles.
