Question

Since nucleotide sequences are more variable than amino acid sequences, you’ll use GAPDH nucleotide sequences to compare across the six taxa you’re analyzing. Suppose that you used BLAST to align all possible pairs of GAPDH sequences among lancelet, lamprey, bass, frog, turtle, and leopard. You would be able to construct the following table showing the percent similarity values across all six taxa.

  Leopard Turtle Frog Bass Lamprey Lancelet
Leopard 100% 83% 80% 81% 76% 74%
Turtle 100% 79% 79% 74% 72%
Frog 100% 79% 74% 71%
Bass 100% 77% 74%
Lamprey 100% 73%
Lancelet 100%

Now you can use this data (similarly to how you used the data in the character table) to build a phylogenetic tree. The distance between species in a tree is directly related to the amount of similarity between their gene sequences. For instance, two species will be closer together if the amount of similarity is high, or far apart if the amount of similarity is low.
