However, the current protocols to derive genome-edited lines require the screening of a great number of clones to obtain one free of random integration or on-locus non-homologous end joining (NHEJ -containing alleles.
Most studies have been based either on genomewide surveys where CNV detection and calling is heavily biased toward copy number changes that cause a large change in dosage, such as deletions, or on locus-specific studies on limited sample sets with error-prone calling of diploid copy number.
It has been suggested that selection, directly on these loci or on loci to which they are closely linked, may be involved in this divergence.
The impact of the genetic model (additive or epistatic) on locus detection power is studied.
However, if non-additive genetic effects are observed, this implies that a part of the variance is explained by interactions between alleles at the same locus or on different loci.

That there were no significant differences in the proportions of loci that matched phage based on whether or not the locus was transcribed, suggests that CRISPR-mediated resistance on a global scale is not regulated based on locus transcription.
When the number of loci is large, relative to the additive model, the dominance model will put little or no selection pressure on loci with small or negligible substitution effects, resulting in greater genetic progress.
To this end, investigators usually focus on loci known or thought to influence phenotypes or be under selection, or on closely linked neutral loci (Hoffmann and Daborn 2007; Reusch and Wood 2008).
Based on these aging-related phenotypes, an overview of the studies performed to date that report on loci or candidate genes associated with renal aging in humans and mice, and the possible roles of some of these genes, is discussed.
By means of coding-gene SNP genotyping, Lamaze et al. (2012) showed that the dynamic of domestic introgression into wild populations was mediated by either positive or negative selection depending on loci.
