One school of thought holds that horses were domesticated in a few sites through breeding for selected traits, with the horses then being distributed to other regions.
Nevertheless these clones were often sufficiently old to have accumulated somatic mutations for selected traits (fig skin color) and at neutral loci (microsatellite markers).
Across all the pig chromosomes and for selected traits, we have carried out a combined analysis of the additive and dominant components of significant QTL positions.
The classical correlation approach compares the degree of association for selected traits between pairs of related individuals, with maximum correlation values that are assumed to be 1.0 for MZ co-twins and 0.5 for DZ co-twins.
Here we propose to make use of publicly available data generated by high throughput technologies to guide the choice of cell lines according to more objective criteria, such as gene expression signatures for selected traits.
Combined studies using GWA mapping, comparative analysis, linkage mapping, resequencing and functional characterization of candidate genes already enabled the identification of candidate genes for selected traits [ 66, 91, 128].
Artificial selection can also have a profound effect on LD in crop plants, with selection for key agronomic traits like flowering behavior, resistances or essential quality parameters causing genetic bottlenecks that lead to extensive conserved haplotype blocks in chromosome regions carrying the responsible gene loci or major QTL for selected traits.
Although a small number of studies have demonstrated phylogenetic signals for selected traits in primates, including mating system [ 76], group size and home range [ 58], we present important new evidence that these traits are all strongly phylogenetically conserved within the Hylobatidae.
It was decided at the outset that the EGA would house both all sequence data generated by UK10K and phenotype data for selected traits, such as height and body mass index (BMI), that were collected by both the TwinsUK and ALSPAC studies.
In any case, cultivated strawberry still represents a great potential source of alleles that might be important for selected traits, since in other species it has been shown that polyploidization is accompanied by changes in the gene expression, and accordingly in phenotypic variation [ 58].
