To make a cladogram, you must first look at the animals you are studying and establish characteristics that they share and ones that are unique to each group. A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. hypothesis about evolutionary relationships. Created by. I would appreciate your thoughts about the best method for drawing a cladogram from STR values. 1) your cladogram of the snail shells, each with the complete data matrix attached, and identification of which characters are synapomorphies, plesiomorphies, autapomorphies, or convergences; 2) a discussion of the cladogram, stating your conclusions, any problems you had, ways the cladograms could be tested further, and so on; However, the appropriate procedure for calculating the probability has yet to be determined. Do either of your cladograms match the accepted cladogram? In this case, the limited amount of molecular data is not enough to sort out a relationship between the different insect groups.

To make a cladogram, you must first look at the animals you are studying and establish characteristics that they share and ones that are unique to each group. For sets of small cladograms the underlying considerations of probability seem straightforward if two cladograms are scored as either matching completely or failing to match. For the animals on the table, indicate whether the characteristic is present or not.
