The phrase "a small replication" is correct and usable in written English.
It can be used in contexts where you are referring to a minor or limited version of something that has been duplicated or reproduced.
Example: "The scientist created a small replication of the original experiment to test the results under different conditions."
Alternatives: "a minor reproduction" or "a limited copy".
If a small replication neighbourhood contains a copy of the species of smallest replicability and just a few (or even zero) copies of more common species, then it has a good chance to replicate, much better than it would had it been surrounded by many more replicators from all the fitter species.
Next, in an independent case-control study of lymphoma, we performed a small replication analysis of associated SNPs that were chosen based on the criteria that multiple SNP-NHL associations were observed in the same gene or gene family.
As with other genome-wide association studies, the power of our analysis was limited by small effect sizes and small sample sizes, particularly a small replication sample.
The city was split into 11 divisions, each a smaller replication of the king's court, comprising a sprawling series of compounds containing accommodation, workshops and public buildings – interconnected by innumerable doors and passageways, all richly decorated with the art that made Benin famous.
A smaller replication confirmed these results.
Likewise, joint analysis may be advantageous for obtaining more precise effect estimates than a smaller replication sample can provide.
They detected subcutaneous adipose biopsies from 776 female twins of European ancestry as well as a smaller replication sample.
When a smaller replication sample was analyzed, the risk allele at rs4141463 was again over-transmitted; yet, consistent with the winner's curse, its effect size in the replication sample was much smaller; and, for the combined samples, the association signal barely fell below the P < 5 × 10−8 threshold.
Since the persistence of the replicator system depends on the survival of the least abundant metabolic replicator species, in fact the question is: why does a very small replication neighbourhood favour the survival of the least fit (i.e., of smallest replicability) species compared to the others?
We also replicated another 17 of 21 CpGs, representing 3 additional gene regions, that had achieved genome-wide significance in the previous study but were not replicated in their small replication population using a Bonferroni correction for multiple tests (Joubert et al. 2012).
miR-18a, miR-181a, and miR-222 showed the highest percentage difference between cases and controls in our study; qRT-PCR of these miRNAs in a small independent replication set of cases and controls, though not statistically significant, replicated the direction of change for all three.
