Figure 3From: Eleven ancestral gene families lost in mammals and vertebrates while otherwise universally conserved in animalsgeneral strategy used for identifying lineage-specific gene family losses. This chart represents the general strategy we adopted to find gene-families that were specifically lost in specific lineages of the tree of life. The 4 main steps are represented in yellow boxes, main results and data in blue boxes, and decisions in red and green boxes.Back to article page
