C1Formal/Neutral
Definition
Meaning
The scientific study of genes, heredity, and the variation of inherited characteristics in living organisms.
Used more broadly to refer to the inherited genetic makeup or constitution of an individual organism or group; the set of principles or factors underlying a particular system, process, or phenomenon (e.g., "the genetics of the stock market").

Mnemonic
Think of a **GENE**ral blueprint for a TICket to life - your **genetics** is the general (gene) instruction set for your biological traits.
Conceptual Metaphor

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'генетика' for metaphorical uses (e.g., 'the genetics of a problem' sounds odd in Russian). In Russian, 'генетика' is almost exclusively the scientific discipline.
- Do not confuse 'genetics' (the science) with 'genotype' (генотип) or 'genome' (геном).
Common Mistakes
- Using 'genetic' as a noun (e.g., 'He has good genetic' X) instead of 'genetics' or 'genetic makeup'.
- Using a plural verb with 'genetics' in its scientific sense (e.g., 'Genetics are complex' X). Correct: 'Genetics is complex.' (It's a field of study).

Frequently Asked Questions
When referring to the scientific field, it is treated as a singular, uncountable noun (e.g., 'Genetics is fascinating'). When referring to the genetic properties of a specific organism, it can sometimes be treated as plural (e.g., 'The genetics of the virus are complex'), though the singular is also acceptable and common.
'Genetics' is the study or the overall system of heredity. 'Genes' are the specific units of heredity, made of DNA, that are passed from parents to offspring. You study genetics, but you inherit genes.
Yes, increasingly so. It can be used to describe the fundamental, originating principles of something non-biological (e.g., 'the genetics of an idea', 'the genetics of a cultural movement'), meaning its essential formative elements.
The related adjective is 'genetic' (e.g., genetic disease, genetic information). The adverb is 'genetically' (e.g., genetically modified).
