Figure S1: The effect of sequence conservation on the relationship between PE and duplicattion age. The dN/dS ration of mouse-rat one-to-one orthologous gene pairs was used as gene evolutionary conservation measurement. (a) Relationship between PE in singletons and the evolutionary conservation of the gene, measured by the ratio of the nonsynonymous (dN) to synonymous (dS) nucleotide distances between the target gene and its rat ortholog. (b) Mean dN/dSdS ratio for each age bin of duplicates. (c) PE in each age bin of duplicates—PE (dup, t) and that of singletons with the same dN/dS ratio—PE *(t). (d) Ratio of PE (dup, t) and PE *(t) in each age bin of duplicates.
