| 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) |

| mahon stock | <botany> An annual cruciferous plant with reddish purple or white flowers (Malcolmia maritima). It is called in England Virginia stock, but the plant comes from the Mediterranean. Source: Websters Dictionary (01 Mar 1998) |

| frozen stock | <cell culture> Because cell lines tend to change their properties with continuous rounds of subculturing, it is common practice to keep stocks of cells frozen (either in liquid nitrogen or at 70_C) and to keep returning to this stock so that experiments are all carried out on cells of comparable passage number. The method also allows strains to be stored for long periods. Cells are usually frozen down in the presence of a cryoprotectant such as DMSO or glycerol. The method is also extensively used for storing semen for artificial insemination. (18 Nov 1997) |
| balanced anaesthesia | A technique of general anaesthesia based on the concept that administration of a mixture of small amounts of several neuronal depressants summates the advantages, but not the disadvantages of, the individual components of the mixture. (05 Mar 2000) |
| balanced articulation | 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 chromosome | <genetics> A chromosome which is unable to pair with its homologue and participate in homologus recombination during meiosis because it contains several inversion mutations (that is, has segments which have become flip-flopped). (09 Oct 1997) |
| 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.
