In contrast to our growing understanding of patterns of additive genetic variance in single- and multi-trait combinations, the relative contribution of nonadditive genetic variance, particularly dominance variance, to multivariate phenotypes is largely unknown. While mechanisms for the evolution of dominance genetic variance have been, and to some degree remain, subject to debate, the pervasive...

Interval information systems are generalizedmodels of single-valued information systems. By introducing a dominance relation to interval information systems, we propose a ranking approach for all objects based on dominance classes and establish a dominance-based rough set approach, which is mainly based on substitution of the indiscernibility relation by the dominance relation. Furthermore, we ...

Four single crosses (VG20 x SGE48, SGE48 x SG35II, VG26 x SG35II, and SG35II x VG20) in opium poppy (Papaver somniferum L.) were analyzed to study the gene actions involved in the inheritance of quantitative traits, namely plant height, branches/plant, capsules/plant, peduncle length, capsule index, stigmatic rays, straw yield/plant, and morphine content. Simple additive, dominance, and epistat...

In 6 studies, the authors examined the perception of dominance complementarity, which is the perception of a target as different from the self in terms of dominance. The authors argue that these perceptions are motivated by the desire for positive task relationships. Because dominance complementarity bodes well for task-oriented relationships, seeing dominance complementarity allows one to be o...

Analysis of generation mean was carried out in six crosses of rice viz., ADT 41 / ADT 46, ADT 41 / CO 47, ADT 41 /TKM 9, ADT 41/ Jeeragasamba, ADT 41/ACM 98003 and ADT 41/AS 90033 for hulling percentage, milling percentage, head rice recovery, kernel length, kernel breadth, kernel L/B ratio, kernel length after cooking, linear elongation ratio and alkali spreading value. The scaling test showed...

We study the effectiveness of simple heuristics in multiattribute decision making. We consider the case of an additive separable utility function with nonnegative, nonincreasing attribute weights. In this case, cumulative dominance ensures that the so-called cumulative dominance compliant heuristics will choose a best alternative. For the case of binary attribute values and under two probabilis...

We establish for the first time a formal relationship between dominance graphs, used for modeling semantics, and grammar formalisms with underspecified dominance links, used for modeling syntax. We present a translation of normal dominance graphs into Unordered Vector Grammars with Dominance Links (UVG-DL) and prove that the configurations of the dominance graph correspond to the derivation tre...

Dominance may be an important source of non-additive genetic variance for many traits of dairy cattle. However, nearly all prediction models for dairy cattle have included only additive effects because of the limited number of cows with both genotypes and phenotypes. The role of dominance in the Holstein and Jersey breeds was investigated for eight traits: milk, fat, and protein yields; product...

Humans use facial cues to convey social dominance and submission. Despite the evolutionary importance of this social ability, how the brain recognizes social dominance from the face is unknown. We used event-related brain potentials (ERP) and functional magnetic resonance imaging (fMRI) to examine the neural mechanisms underlying social dominance perception from facial cues. Participants made g...
