| mathematical genetics | The study of genetic traits by formal analysis, e.g., quantitative genetics, population dynamics, genetic epidemiology, modeling. (05 Mar 2000) |
|---|---|
| medical genetics | The study of the aetiology, pathogenesis, and natural history of human diseases which are at least partially genetic in origin. Compare: clinical genetics, human genetics. (05 Mar 2000) |
| mendelian genetics | The study of the pattern of segregation of phenotypes under the control of genetic loci taken one at a time. (05 Mar 2000) |
| reverse genetics | The technique of determining a gene's function by first sequencing it, then mutating it and then trying to identify the nature of the change in the phenotype. (18 Nov 1997) |
| microbial genetics | The study of hereditary mechanisms of microbes. (05 Mar 2000) |
| classical genetics | That body of method and analysis that perceives genetics as the study of the transmission of genotype from parent to offspring; the study of multiple individuals is essential to it. (05 Mar 2000) |
| clinical genetics | Genetics applied to the diagnosis, prognosis, management, and prevention of genetic diseases. Compare: medical genetics. (05 Mar 2000) |
| modern genetics | That body of method and analysis that perceives genetics as the study of the economy of nucleic acids and associated compounds. (05 Mar 2000) |
| p in population genetics | The frequency of the more common of two different alternative (allelic) versions of a gene. (the frequency of less common allele is q). (12 Dec 1998) |
| multilocal 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) |
| population genetics | <epidemiology, genetics> The study of genetic influences on the components of cause and effect in the somatic characteristics of populations. (05 Mar 2000) |
| selection (genetics) | Differential and non-random reproduction of different genotypes, operating to alter the gene frequencies within a population. (12 Dec 1998) |
| sex determination (genetics) | Process in a given organism, by which the sex genotype is fixed. In humans, sex is established at the time of fertilization by the presence or absence of the y chromosome. (12 Dec 1998) |
| somatic cell genetics | Method for identifying the chromosomal location of a particular gene without sexual crossing. Unstable heterokaryons are made between the cell of interest and another cell with identifiably different characteristics (or without the gene in question) and a series of clones isolated. By correlating retention of gene expression with the remaining chromosomes, it is possible to deduce which chromosome must carry the gene. Human mouse heterokaryons have been extensively used in this sort of work. (18 Nov 1997) |
| sos response (genetics) | An error-prone mechanism or set of functions for repairing damaged microbial DNA. Sos functions (a concept reputedly derived from the sos of the international distress signal) are involved in DNA repair and mutagenesis, in cell division inhibition, in recovery of normal physiological conditions after DNA repair, and possibly in cell death when DNA damage is extensive.
