| balanced diet | A diet containing the essential nutrients with a reasonable ration of all the major food groups. (05 Mar 2000) |
|---|---|
| balanced lethal system | <genetics> A population with non-linked, recessive alleles of a gene, where an individual who has two copies of the recessive allele and is therefore homozygous is dead, while an individual who has only one copy of it, and one copy of a different allele (and is heterozygous) survives. (09 Oct 1997) |
| balanced occlusion | The simultaneous contacting of the upper and lower teeth on the right and left and in the anterior and posterior occlusal areas in centric and eccentric positions within the functional range; used primarily in reference to the mouth, but also arranged and observed on articulators, developed to prevent a tipping or rotating of the denture bases in relation to the supporting structures. Synonym: balanced articulation, balanced bite. (05 Mar 2000) |
| balanced stock | <genetics> A genetic strain of any of several lab organisms (like fruit flies) which can be maintained as heterozygous individuals without requiring constant artificial selection for the heterozygotes, due to a number of lethal recessive genes with the result that the homozygous females are sterile (unable to produce offspring) and the males with the wrong recessive alleles are dead. (Male fruit flies are not homozygous or heterozygous because they only have one allele per particular genetic loci in question). (09 Oct 1997) |
| balanced translocation | <genetics> A number of the chromosomal mutations called translocations, where a segment of DNA abnormally becomes attached to the wrong chromosome, which results in two nonhomologous chromosomes being able to cross over, something which normally can occur only between homologous chromosomes. (09 Oct 1997) |
| mechanically balanced occlusion | A balanced occlusion without reference to physiologic considerations, as on an articulator. (05 Mar 2000) |
| physiologically balanced occlusion | A balanced occlusion that is in harmony with the temporomandibular joints and the neuromuscular system. (05 Mar 2000) |
| dental occlusion, balanced | Dental occlusion in which the occlusal contact of the teeth on the working side of the jaw is accompanied by the harmonious contact of the teeth on the opposite (balancing) side. (12 Dec 1998) |
