All of the species investigated in the first two questions are land plants, and so they share a degree of relatedness (they are much more closely related to each other than to any animal species, for instance), but also represent divergent clades. Assume you are going to study the sequence of a housekeeping gene of interest. Based on what you know about the expected conservation of the game sequence relative to the relatedness of these plant organisms, make a prediction: explain which of these organisms you would anticipate demonstrate the most conserved sequence versus the least conserved housekeeping gene sequence.
