Numbers of loci containing adjacent pseudogenes or their respective isolated entities. Certain adjacent mtDNA genes are expressed from distinct mRNA species. This is the case for the four examples shown. Panel A shows the number of integrations of isolatednd6 and cyt. b pseudogenes in comparison with the integration of fragments that contain both genes in the same arrangement to each other as in mtDNA. Panels B–Dshow the results for the same type of analysis for the couplesnd1 + nd2, nd4 + nd5, andcoxI + coxII, respectively.
