Procedure 1 A Simple Cladogram Cladograms can become very complex. T 17.4 Constructing a Simple Cladogram In order to fully understand how to Derived Trait construct a detailed cladogram, much experience is necessary. The following Placenta Limbs Hair Segmented Jaws Multicellular exercise will help you understand how to construct a simple cladogram. Catfish 1 Based upon Table 17.4, showing Earthworm scrambled derived traits and sample organisms, place a plus in the boxes Sponge for the organism that has a particu- lar trait and a minus if it does not Horse have that trait. This will help you see relationships and aid in the con- Gecko struction of a simple cladogram. 2 Based upon your observations and Paramecium NO Figures 17.6 and 17.7, construct a NONO simple cladogram in the space pro- Kangaroo vided in Figure 17.8, using the data from Table 17.4. Include in your cladogram the nodes and clades, showing their relationships based on their shared derived characters. In the space provided, describe how and why you developed your cladogram.
