Question 1 (30 points total) Please refer to the figure below, which shows a rooted tree of 9 taxa (A -I). Characters Taxa A BC DEFG HI Rooted tree Mapped on that tree are 12 binary characters (1- 12), each of which can take the state of either" or"+". We know that the latest common ancestor of this clade had character states identical to taxon I (a" -"). Using the principle of maximum parsimony, answer the following questions. (2 points) Of the characters that do not show any evidence of homoplasy, which characters are symplesiomorphic for taxa A through E? (2 points) Of the characters that do not show any evidence of homoplasy, which characters are symplesiomorphic for taxa F through H? (2 points) Of the characters that do not show any evidence of homoplasy, which characters are symplesiomorphic for taxa A through D? (2 points) Of the characters that do not show any evidence of homoplasy, which characters are symplesiomorphic for taxa F and G? (2 points) How many equally parsimonious reconstructions are possible for character #6, and how many steps do these reconstructions require? (2 points) How many equally parsimonious reconstructions are possible for character #10, and how many steps do these reconstructions require
