Figure 2

Evolutionary distribution of FAM20 gene number. An idealized evolutionary tree (modified from [10]) is shown with the number of FAM20 genes identified in several genomes as described in the text. The gene numbers are supportive of a single gene duplication event occurring in invertebrates (at least in insects) and multiple gene duplication events occurring in higher vertebrates.
