The phrase "a shallow population" is correct and usable in written English.
It can be used to describe a group of people that lacks depth in terms of knowledge, understanding, or character.
Example: "The documentary highlighted the issues faced by a shallow population that prioritizes superficial values over meaningful connections."
Alternatives: "a superficial population" or "a shallow demographic".
Despite a shallow population structure, clustering analyses partitioned the microsatellite data set into separate groups of samples corresponding roughly to geography.
Overall, the most common haplotypes (1, 8, and 11, Appendix 1) were found to be widespread suggesting a shallow population substructuring of mtDNA across most of the geographic distribution of An. gambiae s.s. Figure 2A shows the clustering of populations based on FST values derived from the ND5 sequence data.
The apparent shallow differentiation between west and southern African S-form samples is consistent with previous studies pointing to an overall shallow population differentiation within this form (Lehmann et al. 1999, 2003).
A deep reference population, named TG4, made up of generations 1 to 4, was compared to a shallow reference population, named TG2, made up of generations 1 and 2. TG2 resulted in an accuracy that was about 15% lower compared to TG4 in the sixth generation after training.
The three other genetic architectures showed a consistent but different pattern from the low-unequal architecture, with GBLUP performing best in generation 1, while PLSR performed best in generation 10 for approaches that used a shallow reference population, and GBLUP performed best in generation 10 for approaches that used a deep reference population (Table 3).
Analysis of the most variable region of the mitochondrial control region revealed shallow population divergence and a lack of phylogeographic structure in B. microlepis, with several haplotypes shared between individuals from very distant parts of the lake.
In generation 1, selection on MEBV from a shallow reference population always resulted in a greater response in G ¯ compared to selection on MEBV from a deep reference population (Table 3).
Use of a shallow reference population, most closely related to the selection candidates, gave early benefits while in later generations, when marker effects were not updated, the estimation of marker effects based on a deeper reference population did not pay off.
Despite this shallow population structure, clustering analyses partitioned the data set into separate groups corresponding roughly to geography, indicating that each region hosts a distinct population of the fungus.
Gene flow reduces population differences and promotes shallow population genetic structure.
Importantly, the shallow population structure within sectors shows that gene-flow is similarly reduced between more closely related populations.
