Question

Animals cladogram 10 points. Use the following characters and list of organisms/groups of organisms to create a cladogram. A few of these, such as the Hox genes, we did not discuss in class, but you will find them described in chapter 34. You can use numbers to refer to the characters on your cladogram, and many "tick-marks" will represent multiple characters (like our plant cladogram we did in class). Don't let perfection be the enemy of completion of this assignment :) I want this to be a learning/summarizing tool for you. Begin with deuterostome development as the character that the entire clade possesses, and your outgroup is the echinoderms.

Answer 1

Hox genes present in Cnidaria ( can be placed before Echinoderms).
