    Identifying the Key Genes for Regeneration

    Scientists at Work

    (9 min 55 sec) Planarians have an amazing ability to regenerate lost tissues. In this video, scientists knock out two different genes in planaria to start to understand how the process works—and they generate animals with two heads and two tails!

  • Stalking the Genetic Basis of a Trait

    Stalking the Genetic Basis of a Trait

    Activity

    In this activity students analyze data on the expression of the tb1 gene and use it to formulate an explanation as to how a specific difference in the corn version of the gene explains the phenotype of less branching.
