6: Genetic Basis of Complexity

  • Page ID
  • In Genetic Toolkit, we examined how gene expression (and cell fate) is determined by local activators and on/off signal transduction pathways. We considered "wiring diagrams" for understanding how master regulatory genes can affect a suite of downstream genes in competent cell types. In this module, we will take a brief look at how these switches can evolve taking both organismal complexity and genetic complexity into consideration.
