- Sainmhíniú difference between the average phenotype of all cases that have the Aa genotype at a particular marker and the expected value half way between all cases that have the aa genotype and the AA genotype Tagairt "University of Tenessee. GeneNetwork. Glossary of Terms and Features. Dominance Effects, http://artemis.uthsc.edu:85/glossary.html [25.6.2014]"
- Nóta "For example, if the average phenotype value of 50 individuals with the aa genotype is 10 units whereas that of 50 individuals with the AA genotype is 20 units, then we would expect the average of 100 cases with the Aa genotype to be 15 units. We are assuming a linear and perfectly additive model of how the a and A alleles interact. If these 100 Aa cases actually have a mean of 11 units, then this additive model would be inadequate. A non-linear dominance terms is now needed. In this case the low a alleles is almost perfectly dominant (or semi-dominant) and the dominance deviation is -4 units.The dominance effects are computed at each location on the maps generated by the WebQTL module for F2 populations (e.g., B6D2F2 and B6BTBRF2). Orange and purple line colors are used to distinguish the polarity of the dominance effects. Purple is the positive dominance effect that matches the polarity of the green additive effect, whereas orange is the negative dominance effect that matches the polarity of the red additive effect.Note that dominance deviations cannot be computed from a set of recombinant inbred strains because there are only two classes of genotypes at any marker (aa and AA, more usuually written AA and BB). However, when data for F1 hybrids are available one can estimate the dominance of the trait. This global phenotypic dominance has almost nothing to do with the dominance deviation at a single marker in the genome. In other words, the dominance deviation detected at a single marker may be reversed or neutralized by the action of many other polymorphic genes. [Williams RW, Dec 21, 2004; Sept 3, 2005]. It is equal to the difference between the genetic value [ IATE:1254760 ] and the breeding value [ IATE:1254761 ].See also: The Mendelian Basis of Coninuous Traits, http://evolution.unibas.ch/teaching/qua_genetics/downloads/01_pres_160310.pdf [25.6.2014]"
