- What is a monophyletic clade? What is its difference between paraphyletic and polyphyletic clades?arrow_forwardPhylogenetic trees are used to show the evolutionary relationships among various biological species and are usually based upon shared derived characters. In constructing phylogenetic trees, it is useful to first draw up a character table to show the presence or absence of characters among the various groups of organisms being studied. a. Draw up a character table based upon the following shared derived characters of land plants: flowers, seeds, vascular tissues, and dependent embryos. Your character table must include the names/descriptions of the plant groups that are being characterized. b. Construct a phylogenetic tree based on this data.arrow_forwardA cladogram used in a comparison of morphology among taxa had equal length branches, but when looked at in a blast webpage using the given gene sequence, the branches all had different lengths.

- In the last lab while creating a phylogenetic tree using PAUP/CIPRES, Fagus grandifolia was specified as the outgroup . Why is this step important? If the outgroup is not specified, PAUP or CIPRES will produce an unrooted tree in which outgroup is not connected to the rest of the tree by a common ancestor If the outgroup is not specified, PAUP or CIPRES will produce an unrooted tree in which the outgroup might not branch off prior to the common ancestor of the organisms under study O If the outgroup is not specified, PAUP or CIIPRES will produce an unrooted tree.
