dominance /dom·i·nance/ (dom´ĭ-nans)
1. the state of being dominant. 2. in genetics, the full phenotypic expression of a gene in both heterozygotes and homozygotes. 3. in coronary artery anatomy, the state of supplying the posterior diaphragmatic part of the interventricular septum and the diaphragmatic surface of the left ventricle. incomplete dominance failure of one gene to be completely dominant, heterozygotes showing a phenotype intermediate between the two parents. lateral dominance the preferential use, in voluntary motor acts, of ipsilateral members of the major paired organs of the body.
dominance [dom′inəns] Etymology: L, dominari, to rule the property of an allele in which the allele is fully expressed in the phenotype, even when only one copy of the allele is present. See also autosomal-dominant inheritance, recessive allele, segregation. dominant, adj. Dominance Genetics The ability of a dominant gene to express itself in a phenotype, when the gene is paired with another (recessive) gene that would have expressed itself in a different way Neurology The tendency of one brain hemisphere to be more controlling than the other in mediating neural activity Psychiatry A predisposition to playing the controlling role when interacting with others Sexology See Domination Transplant medicine See Donor dominance, Recipient dominance dominance [dom´ĭ-nans] 1. the supremacy, or superior manifestation, in a specific situation of one of two or more competitive or mutually antagonistic factors. 2. the appearance, in the phenotype of a heterozygote, of one of two mutually antagonistic parental characters.
dominance 1. the supremacy, or superior manifestation, in a specific situation of one of two or more competitive or mutually antagonistic factors or animals. 2. in genetics, alleles which fully express their phenotype when present in the heterozygous state. dominance aggression behavior by an animal that asserts its dominance over another or a human, such as competing for food, resisting control measures, or assuming dominant postures. dominance deviation a deviation from gene additive action due to dominance. incomplete dominance when a heterozygote displays the effects of two alleles at the same location; the alleles are said to be incompletely dominant or co-dominant. location dependent dominance behavior in which an animal is dominant when in its home territory, but it becomes subordinate outside that territory. dominance relationship
probability of relatives having the same genotype. dominance Genetics The ability of a dominant gene to express itself in a phenotype, when the gene is paired with another (recessive) gene that would have expressed itself in a different way Neurology Cerebral dominance The tendency of one
brain hemisphere to be more controlling than the other in mediating neural activity Psychiatry A predisposition to play a controlling role when interacting with others Sexology See Domination.
