| genetics, population | The study of the genetic composition of populations and of the effects of factors such as selection, population size, mutation, migration, and genetic drift on the frequencies of various genotypes and phenotypes. (12 Dec 1998) |
|---|---|
| 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) |
| molecular genetics | <study> The study of the flow and regulation of genetic information between DNA, RNA, and protein molecules. (09 Oct 1997) |
| 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) |
| human genetics | The study of the genetic aspects of humans as a species. Compare: medical genetics. (05 Mar 2000) |
| 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) |
