dominance

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

/dom·i·nance/ (dom´ĭ-nans)

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.

(dŏm′ə-nəns)
n.
The condition or fact of being dominant.

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.
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

dominance

The power of a gene to exert its influence whether the other member of the gene pair is identical or dissimilar. GENES occur in pairs at corresponding positions (loci) on each of the paired CHROMOSOMES. A gene that has its effect only if paired with an ALLELE of the same kind is said to be RECESSIVE. The effect of a dominant gene paired with a recessive gene will be the same as if both genes had been identical to the dominant gene, but every cell in the affected person's body, including those producing sperms and eggs, contains the recessive gene. Such a person is said to be HETEROZYGOUS for that gene. When the sperms and eggs are produced, only one of the pair of chromosomes is included, so there is a 50/50 chance that this will be the one with the recessive gene. Should a sperm with the recessive gene fertilize an egg which also has the recessive gene, the recessive characteristic will be expressed because there is no other genetic material for the characteristic.

dominance

  1. a genetic interaction where one ALLELE of a gene masks the expression of an alternative allele in the HETEROZYGOTE, so that the PHENOTYPE is of that form controlled by the dominant allele. For example, gene A has two alleles A1 and A 2:
  1. but when heterozygous, A 1/ A2 = black phenotype. Thus A1 is dominant to A 2, with A2 ‘recessive’ to A1. In molecular terms, the A1 allele is coding for a protein of such quality and quantity to allow the normal amount of black pigment to be produced, even though the A2 allele is not coding for a normal enzyme. See also CODOMINANCE, INCOMPLETE DOMINANCE.
  2. the preponderance of one species within an ecological COMMUNITY, for example, oaks in oak woods.

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.
