The data below, excerpted from a paper by Heui-Soo Kim and Osamu Takenaka, are short DNA sequences from five species: human, chimpanzee, gorilla, orangutan, and baboon. The sequences, each 50 bases long, represent a short piece of the SRY gene located on the Y chromosome. The complete human sequence is given. The sequences for the other four species are shown only where they differ from the human sequence.
At the top of the next page is the UPGMA gene tree constructed from these data.
What is the length of the branch which connects the baboon sequence to the rest of the UPGMA gene tree?
A. 0.095
B. 0.19
C. 0.22
D. 0.38
E. 0.075
