This difference may be explained by a higher level of divergence between SPANX-N genomic regions compared to the recently amplified SPANX-A/D loci.
The high level of divergence between dipteran and lepidopteran apoLp-IIIs sequences may reflect the plasticity of apoLp-IIIs, as divergent amino acid sequences can fold into proteins with similar tertiary structures.
The high level of divergence between the two haplotypes of N2 and CB4856 in these regions indicates an ancient origin.
Again, frequent copy number variations and a high level of divergence between homolog were observed common among accessions.
In addition, the group is characterized by widespread heteroplasmy in mitochondrial sequences, including a high level of divergence between heteroplasmic haplotypes within individual specimens [ 38].
In most cases, the phylogenetic trees had shown very poor resolution (perhaps due to within-gene recombination) or very high level of divergence between cyanobacterial and cyanophage homologs.
Considering the high level of divergence between OTU and the low divergence within each OTU, as well as the strong support for each OTU in the phylogenetic reconstruction, it appears that each OTU may be distinct.
We saw no evidence of cross mapping between host and parasite genomes, as expected, owing to the availability of reference genomes for both organisms and the high level of divergence between them (data not shown).
A strong shift in allozyme frequencies together with a high level of divergence between alleles and a low number of 'hybrid' individuals were observed between the northern and southern groups using the phosphoglucomutase gene.
Consequently, inside the rearrangement there is a high level of divergence between the chromosome types, with the majority of differences representing fixed differences between ZAL2 and ZAL2m (Thomas et al. 2008).
