The attraction is a group of authors like Andre Dubus III, whose book "House of Sand and Fog" was a recent Oprah selection; Laura Shaine Cunningham, left, author of "A Place in the Country," and Nicholas Baker, whose "Double Fold" offers a controversial view of certain library practices (like replacing newspaper archives with microfilm).
However, in T. commodus, the sign of the phenotypic relationship between reproductive effort and longevity is known to be diet-mediated [34], and a recent selection experiment [36] suggests that antagonistic pleiotropy between male calling effort and longevity may occur under some environmental conditions.
The region of increased homozygosity is broad in African Americans (implying a recent selection event) but narrow in Europeans (perhaps indicating an older selective event, reduced in size by more generations of recombination).
The similarity of the monotonic ascending DD-frequency gradients for the three younger SNPs is consistent with the identified positive selection being a recent and possibly ongoing process.
Of great excitement is a recent application, microarray-based genomic selection (MGS), which can serve as a bridge to next-generation resequencing technologies, enabling the complete ascertainment of sequence variation in large, specific regions of the human genome[18], [19], [20].
Despite these advances, there are still regions whose functions or mechanisms of action are still unknown or not fully understood; an example of this is a recent study that demonstrates natural selection also acting on non-coding regions (Mu et al. 2011).
Genomic selection (GS) is a recent approach that is being applied in crop breeding to make decisions for advancing germplasm from one generation to the next.
Artificial selection could be a recent process in this species or not strong enough to have caused genetic differentiation between wild populations and populations exposed to management practices, because human-induced and naturally occurring gene flow may rapidly counteract the effects of artificial selection.
As a rule, the greater the linkage disequilibrium associated with a gene, the more likely that the gene has been under recent selection.
In the case of DGAT1 there has been recent selection for the ancestral allele after possible earlier selection for the mutant.
