You are working with 6 different bacteria: A, B, C, D, E and F. Based on genetic sequencing data, you determine that they all share a gene for maltose catabolism. Bacteria A, C and D share a gene for toxin production. Bacteria B and F share a gene for flagellum production. Bacteria C and D share a gene for anamoxosome production. In addition, each bacterium has at least 1 unique gene.

A) How many external nodes would this phylogenetic tree have?

B) How many internal nodes would this phylogenetic tree have?

C) How many clades would this phylogenetic tree have? Hint: remember that all bacteria together count as one clade too.
