Figure 1From: Accelerated exon evolution within primate segmental duplicationsDetecting accelerated exon evolution. Genomic regions containing transcripts are extracted from a masked genome. Whole-genome shotgun (WGS) reads of one or more species are aligned against these regions. All alignments are summarized within a composite sequence that records all high-quality differences present in at least two alignments. Rates of differences per nucleotide within exons and neighboring introns are computed, and a likelihood-ratio test is applied.Back to article page
