The reduction of allelic variation in A. oryzae mirrors the overall reduction of genetic variation in these isolates compared with A. flavus (Gibbons et al. 2012b).
Furthermore, interaction resulted in the reduction of unpredictable variation in all conditions, suggesting a role for communicative interaction in eliminating unpredictable variation.
It is often linked to the "six sigma" quality strategy because of the methodology's emphasis on the reduction of process variation (which six sigma intends to control up to the sixth standard deviation of possible failure).
With more feed items included in the formulation, the complementary nature of nutrients in different ingredients promotes the reduction of nutrient variation as reported by Zhang and Roush (2002).
In addition, the reduction of the variation remains almost unchanged when the loss is large.
In particular, when the loss is medium, the reduction of the variation is remarkable.
Participants perceived that these guidelines improved patient safety through the reduction of unmotivated variation.
Purifying selection results in the reduction of genetic variation through the elimination of maladjusted alleles and consequently of the mutations that caused the maladjustment.
In selective sweeps, the reduction of genetic variation is lowest at the site of directional selection and not as great at distant sites due to recombination, although asymmetry in the valleys of reduced heterozygosity may provide imprecise information about the location of the sweep [ 25].
The low probability of long-distance dispersal and successful colonization, the reduction of genetic variation in founding populations and the challenges of adaptation to new environments are all features that combine to affect processes of evolution in island archipelagos, particularly speciation.
