Given that although pleiotropy does occur, its effects seem somewhat limited and cannot alone explain the large clusters of multiple different trait QTL all grouping in loose clusters throughout the genome.
82 Using an intercross between wild and domestic chickens, QTL clusters were found that indicated multiple different trait types were overlapping, 13 with loci for comb size (a sexually selected ornament in the chicken) overlapping with onset of sexual maturity loci, 15 as well as with bone density and egg production traits.
If pleiotropy is occurring, QTL studies between wild and domestic animals should show an overlap between the multiple different domestication traits.
82, 83 These studies imply that the loci for tameness show pleiotropic effects on multiple different domestication syndrome traits, though in these instances close linkage between different genes affecting each trait could also be a potentially plausible explanation.
The detection of multiple QTLs for different traits may facilitate an improved strategy for developing lines with increased lodging resistance.
Multiple QTL for different traits mapped on LG21 overlapped each other, implying pleiotropy and/or tight linkage.
It also allows for a high volume generic chip to be produced, which will lower assay cost per individual and will limit heterogeneity of genomic information compared to using multiple assays for different traits.
Omy12 and Omy14 were found to be "hotspot QTL regions" (i.e., multiple QTL for different traits), and further support for the importance of these regions comes from QTL for growth (Wringe et al. 2010) and osmoregulation (Le Bras et al. 2011).
Videos of multiple actors performing multiple actions while conveying different traits with different levels of intensity allow for flexibility in their combination to enable testing of various theoretically motivated hypotheses relating to the perception of human action and underlying processing mechanisms.
This can occur if the same genes influence multiple traits, if genes for different traits are closely linked on chromosomes, or if environmental effects (e.g., temperature or diet) simultaneously influence multiple traits.
