| variation (genetics) | The phenotypic differences among individuals in a population. (12 Dec 1998) |

| antigenic variation | The phenomenon of changes in surface antigens in parasitic populations of Trypanosoma and Plasmodium (and some other parasitic protozoa) in order to escape immunological defense mechanisms. at least 100 different surface proteins have been found to appear and disappear during antigenic variation in a clone of trypanosomes. Each antigen is encoded in a separate gene. Antigenic variation is also known to occur in free living Protozoa and certain bacteria. (18 Nov 1997) |

| variation | In genetics, deviation in characters in an individual from those typical of the group to which it belongs, also, deviation in characters of the offspring from those of its parents. (18 Nov 1997) |
| phase variation | <microbiology> Alteration in the expression of surface antigens by bacteria. For example: Salmonella can express either of two forms of flagellin, H1 and H2, that are coded by different genes. Control of which form is expressed is brought about by inversion of the promoter for the H2 gene, which if functional (noninverted) is associated with the expression of H2 and the production of a repressor of the H1 gene. Inversion occurs about every 1000 bacterial divisions and is under the control of another gene, hin, that is within the invertable sequence. (31 Dec 1997) |
| coefficient of variation | The ratio of the standard deviation to the mean. (05 Mar 2000) |
| contingent negative variation | An increasing negative shift of the cortical electrical potentials associated with an anticipated response to an expected stimulus. It is an electrical event indicative of a state of readiness or expectancy. (12 Dec 1998) |
| somaclonal variation | The variation between individuals in a clone, particularly in plant clones. While the objective is usually to grow clones without variation, somaclonal variation does provide the opportunity to generate new plant types that would be harder or impossible to generate by conventional plant breeding. (14 Nov 1997) |
| isotypic variation | <immunology> Variability of antigens common to all members of a species, for example the five classes of immunoglobulins found in humans. See: idiotype and allotype. (18 Nov 1997) |
| observer variation | The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material). (12 Dec 1998) |
| behavioural genetics | The study of heritable factors in behavioural patterns, as by pedigree analysis, biochemical abnormality, or karyotypic analysis. (05 Mar 2000) |
| biochemical genetics | The study of genetics in terms of the chemical (biochemical) events involved, as in the manner in which DNA molecules replicate and control the synthesis of specific enzymes by the genetic code. (05 Mar 2000) |
| biometrical genetics | <study> The mathematical approach to the study of the inheritance of different phenotypes, or physical characteristics, as a result of plant or animal breeding. (09 Oct 1997) |
| Galtonian-Fisher genetics | The genetics of measurable traits determined by multiple loci which make contributions that are independent, additive, and approximately equal. Synonym: multilocal genetics. (05 Mar 2000) |
| galtonian genetics | The study of traits by analysis of the first two moments of metrical data; the preferred method for analysis of traits following the multivariate gaussian distribution. (05 Mar 2000) |
| palindrome in genetics | A palindrome is a word that reads the same in both directions as, for example, the names eve or anna. In genetics, a palindrome is a DNA or RNA sequence that reads the same in both directions. The sites of many restriction enzymes that cut (restrict) DNA are palindromes. Palindromic rheumatism is a form of joint inflammation whereby the joints involved appears to change periodically from one region of the body to another and back again. (12 Dec 1998) |
| genetics | <study> The study of the patterns of inheritance of specific traits. (09 Oct 1997) |
