The phrase "a local duplication of" is correct and usable in written English.
It can be used when referring to a specific instance or copy of something that exists within a localized context or area.
Example: "The researchers discovered a local duplication of the species in the nearby forest."
Alternatives: "a regional copy of" or "a nearby replica of".
Tenascin-W may have evolved as a result of a local duplication of the ancestor of tenascin-C and -R.
In addition, the teleost fishes have a local duplication of one of these orthologs resulting in three members of this family located on the same chromosome (Fig. 2).
We hypothesized that the two alleles arose from a local duplication of the CDC11 locus and amplified and sequencing nearby genes to identify those without mixed peaks that would define the boundaries of the duplication.
Vertebrate gphα and gphβ were generated by a local duplication of the ancestral forms of gpa2 and gpb5, followed by a relocation of gphβ into a new environment whereas gphα was retained in the gpa2-gpb5 environment.
Considered together, the genomic and protein evidence suggests that an ancient MPEG1 gene underwent a local duplication to produce a common ancestor of perforin and C6.
The topology of the tree indicates a local duplication before the split of actinopterygians and sarcopterygians followed by block duplications and also some additional local duplicates in the fish lineage.
Our model suggests that vertebrate gphα and gphβ were generated by a specific local duplication of the ancestral forms of gpa2 and gpb5, followed by a translocation of gphβ to a new environment whereas gphα was retained in the gpa2- gpb5 locus.
The tree also indicates a local duplication before the divergence of actinopterygians and sarcopterygians and additional fish specific duplications.
It is interesting that PNOC and POMC are the result of a local duplication because they are the most divergent sequences in the quartet of opioid peptide precursors.
The gene is located next to the PNOC gene in chicken and in the teleost fishes, suggesting that these two genes are a result of a local duplication.
The two SWS1 genes are located adjacent to each other on the same linkage group (LG8) approximately 8 Kb apart (see Table 1), and are thus most likely the result of a local duplication.
