Figure 4From: Gene conversion and purifying selection shape nucleotide variation in gibbon L/M opsin genesDistribution of gene conversions between the L and M opsin genes in gibbons detected by GENECONV. The top line represents the exon-intron structure of the L/M opsin genes. The arrows represent the area covered by gene conversions detected for pairs of L and M opsin genes in the five gibbon species (see Figure 3 legend for the abbreviations of species names).Back to article page
