There are major axes ( internodes ), such as A-G and E-E", which are pathways of anagenesis and branching points ( nodes ) where the evolutionary process called cladogenesis occurs. In this laboratory investigation, you will use BLAST to compare several genes, and then use the information to construct a cladogram. Remember to start with. How to design and interpret cladograms based on derived characters Materials: 1.
