| quantitative genetics | The formal study of measurable genetic traits, traditionally but not necessarily confined to galtonian genetics. (05 Mar 2000) |
| terminator regions (genetics) | DNA sequences which signal the termination of transcription. (12 Dec 1998) |
| trans-activation (genetics) | Increased rate of gene expression directed by either viral or cellular proteins. These regulatory factors (diffusible gene products) act in trans -- that is, act on homologous or heterologous molecules of DNA. (cis-acting factors act only on homologous molecules.) (12 Dec 1998) |
| translocation (genetics) | A type of aberration characterised by fragmentation of a chromosome and transfer of the broken-off portion to another chromosome, often of a different pair. (12 Dec 1998) |
| transplantation genetics | Genetics as applied to the transplanting of tissues from one animal to another. (05 Mar 2000) |
| epidemiological genetics | The study of genetics as a phenomenon of defined populations by the criteria, methods, and objectives of epidemiology rather than of population genetics. (05 Mar 2000) |
