Summary
In this long term computer based simulation, students play with a fabulous FREE software program called Biologica developed by the Concord Consortium. It offers an in depth, virtual experience exploring Mendelian inheritance patterns in dragons. Activities increase in complexity from initial modules introducing dragons and their chromosomes to later activities that require problem solving skills and the integration of many levels of prior knowledge. In the program, you can manipulate dragon chromosomes, breed dragons, explore pedigrees, and more. There are fantastic puzzles along the way: Which gametes should you select to breed a purple, fire breathing, boy dragon? What happens if you change the DNA sequence? Can you figure out the genotype of invisible dragon parents from the phenotypes of their offspring?

Objectives
Can explain and use the relationship between genotype and phenotype to explain inheritance patterns.
Can take genotype information from 2 parents, model the creation of gametes by independent assortment, and use those gametes to create offspring.
Can explain the relationship between DNA, genes, and chromosomes.
Can explain how the inheritance of sex chromosomes contribute to an individual’s sex and to X-linked traits.
Can use Punnett squares to predict the possible allele combinations in the offspring given the genotypes of the parents.
Can understand the role of mutations in creating variation in phenotypes.
