Sentence examples for paucity of variation from inspiring English sources

As in Europeans, there is an extreme paucity of variation in these populations as compared to Africans (Figure 2), as well as large EHH when compared to the same alleles in Africans (Table 1).

We observed that when we used the rhesus monkey (that diverged from humans 20 25 MY ago) as outgroup and applied the Kolmogorov-Smirnov neutestity test, we do not observe along the human-rhesus lineages the paucity of variation downstream of intron 6 that is observed for human polymorphisms.

Although African and Asian/Oceanian samples include individuals with diverse origin and therefore, are structured, we would not expect the paucity of variation observed downstream of intron 6, or the excess of rare alleles in the African sample to be an artifact of our sample composition.

Colonizations are usually accompanied by adaptive changes, but it is a long standing question whether fast adaptations are constrained by the initial paucity of variation caused by a genetic bottleneck of only few arriving individuals [ 2].

This paucity of variation is observed in all lin genes except linKLMN, further supporting the prediction that these genes, including core downstream components such as the β-ketoadipate pathway encoding linGHIJ, have been acquired by horizontal transfer.

The A haplogroup, however, also exhibited a significant paucity of genetic variation compared to neutral expectations (p < 0.005), suggesting the possibility of recent positive selection acting to remove linked variation in this clade, but the very low level of polymorphism (three segregating sites) precludes further analysis of this clade with neutrality tests (Table 2).

Perhaps the most striking pattern in the data was the paucity of genetic variation across vast geographic distances.

The paucity of sequence variation in the Cyt b sequences was consistent with the less resolved tree based on the mtDNA control region sequences.

However, given the relative paucity of genetic variation and the small magnitude of the difference of the inferred ages of nodes (both of which are likely to increase error), these age estimates should be regarded as approximations.

Due to the paucity of known sequence variations in the human SLC26A5 gene, evaluation of a patient-control cohort was undertaken to seek additional sequence variations in SLC26A5 and explore the hypothesis that variations in prestin might modify the degree of hearing loss caused by an independent etiology.

There is paucity of data on seasonal variation in pulmonary tuberculosis (TB) in developing countries contrary to recognized seasonality in the TB notification in western societies.
