Sentence examples for variance in the selection from inspiring English sources
This proportion of the genetic variance in the selection candidates captured by SNPs in the reference population is the maximum accuracy of genomic prediction for those populations based on the used SNP chip [ 39].
Then, natural selection acts on the phenotype, where we implement stabilizing selection for optimal trait θ W with variance in the selection surface V S ; the inverse of this variance represents the strength of selection.
For across-population genomic prediction, the genetic correlation between populations has to be taken into account, because it limits the part of the genetic variance in the selection candidates that can be explained by the reference population.
This indicates that only 80% of the genetic variance in the selection candidates was captured by the markers in the reference population, due to differences in LD and allele frequencies of QTL between the reference population and the selection candidates.
Another deterministic formula using population parameters overestimates the accuracy of across-population genomic prediction, because the SNPs in the reference population cannot capture all of the genetic variance in the selection candidates.
However, this formula may still be useful because of its simplicity, and is expected to be much more accurate when the proportion of genetic variance in the selection candidates is known with reasonable accuracy and included in the formula.
This is reflected in the variance in voxel selection across the 50 different Split-half analyses for each IQ measure (see Fig. 4).
Strong stabilizing selection should erode additive genetic variance in the traits under selection.
Suitable visualizations of the results in order to help the assessment of the robustness of the designs against possible inaccuracies of the assumptions about the true values of the variance components used in the selection of the designs are recommended.
Therefore, while there is a large variance in the level of selection among the different genes, this result supports a small but significant relaxation in the level of selection pressure following gene duplication.
The results of our study suggest a lack of genetic constraint to the evolution of life history traits in this population and hence to the maintenance of genetic variance in the direction of selection.
