From: UVPAR: fast detection of functional shifts in duplicate genes

Figure 1

A) Gene duplication followed by divergence of paralogs and the split of two lineages. The gene A duplicates to give rise to identical A and A' paralogs. These paralogs accumulate differences (becoming genes A and B). Then, the lineages split in such a way that each daughter species conserve the A and B genes, which can then be called A 1 and B 1 for the first species and A 2 and B 2 for the second species. B) Different rates of evolution, in this case acceleration in the B 2 gene. If this occurs, the genes of the first species (A 1 and B 1 ) will be more similar than the genes of the second species, a difference that could be detected comparing the sequences with UVPAR.
