Figure 2

An example phylogeny. The phylogeny shows the visual similarities of 16 classes, where each class is a set of 25 images of Drosophila cells with single gene knockdown. The gene classes are specified by their CG numbers. As can be learned from the phylogeny, the resulting phenotypes when knocking down genes CG10895 and CG10873 (which have a substrate-kinase relationship) are very similar to each other, while the phenotypes of gene CG12284 (cell death), CG3733 (unknown function) and untreated cells are different from the other cells.
