    Lab
    Students learn the principles of independent assortment and gene linkage in activities that analyze the inheritance of multiple genes on the same or different chromosomes in hypothetical dragons. The concepts of independent assortment of chromosomes during meiosis and random fertilization are modeled with linked genes.

    Demystifying Punnett Squares Simulation
    Free Multimedia
     
    Lab

    In the simulation, students breed pairs of mice with different fur colors and observe the phenotypic ratios in the resulting offspring.  Students select one breeding pair from the nest to investigate the ratios of fur color phenotypes, genotypes, and sex.  Students then click “breed”.  After each parent pair breeding, the resulting litter of offspring is shown, along with a pie chart, which updates to display the ratios in the total number of offspring for those parent mice.

    Example questions to ask students:
    Why do some of the pie charts change as you breed the mice?
    Why do the pie charts stabilize?
    Where are the numbers different from the ratios in Punnett Square? Where are they the same?
