The phrase "a level of divergence" is correct and usable in written English.
It can be used to describe the extent or degree to which two or more things differ or deviate from each other.
Example: "The study revealed a level of divergence in the opinions of the participants regarding the proposed policy changes."
Alternatives: "a degree of difference" or "an extent of variation".
Assuming a rate of mitochondrial COI evolution of 2% per million years [ 57], we estimate the two species diverged in the late Pleistocene, around 700,000 years before present, a level of divergence less than most Neotropical bird sister species [ 58].
All of the shared genes have a level of divergence ranging from ∼50%–95%, which is much higher than the level found on the chromosome as discussed below.
Even with such a level of divergence, the gene expression pattern of some olfactory receptor genes in the maxillary palp are very similar in these two species, indicating the possible functional conservation of the organ [36].
A 0.3% similarity threshold was empirically chosen as a level of divergence that would allow for sequence errors that might occur between identical sequences, about 5 nucleotide positions in the approximately 1.5 kb 16S sequence.
Thus, this lineage exhibits a level of divergence more typical of an entire staphylococcal species.
This analysis also indicated that D. melanogaster orthologues were likely to be present for many of the putative CstyOBPs, although a few small C. stygia specific clades potentially indicate a level of divergence within the blowfly.
Given such a history we should expect a level of sequence divergence of 1.3 1.6% [ 23]; in fact between these repeats we observe 1.1% sequence divergence (excluding indels).
The genome sequence of several sensu stricto species [ 4, 5] revealed a level of nucleotide divergence comparable to that between humans and birds yet a level of structural variation comparable to that between humans and chimps [ 6].
The markers show a level of intron divergence that is of a similar magnitude as ITS, which is one of the most informative and broadly used markers in plant molecular systematics.
This method is capable of harvesting all elements identified by earlier computational methods while also locating previously undetected copies, down to a level of ∼50% divergence between paired LTRs, well beyond the point of most element survival.
For example, over a level of synonymous divergence similar to Xenopus paralogs, older paralogs of the fungus and plant polyploids Saccharomyces cerevisae and Arabidopsis thaliana are more constrained than younger ones [ 6].
