Relationship between "ortholog hit ratio" (see Figure 4) and assembly coverage (a,b) as well as B. mori ortholog length (c, d). Figures on the left refer to E. propertius, figures on the right refer to P. zelicaon. Where this ratio is 1.0, the gene is likely fully assembled. Ratios greater than 1.0 can indicate insertions in unigenes. Overall distributions of ortholog hit ratios for contigs and singletons also shown (e,f).
