a) (5 points) Assume that the following similarity matrix has been computed for six genes: S= amoan A B C D E F A 1 B C 0.15 0.2 1 0.4 1 D 0.6 0.3 0.12 1 E 0.2 0.8 0.22 0.1 1 F 0.6 0.5 0.24 0.8 0.14 1 Draw the result of applying single-linkage clustering to the data. Your answer should be in the form of a dendrogram (a.k.a a tree).
