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.
