Phonetic Transcription

/ˈæd.ɪ.tɪv ˈvær.i.əns/

Meaning and Usage

"Additive variance" refers to the concept in statistics and genetics that denotes the portion of variance in a trait that can be attributed to the additive effects of alleles (gene variants). It is commonly used in the context of quantitative genetics, where the total genetic variance is broken down into components, one of which is additive variance. This term is more prevalent in scientific and academic writings related to genetics and statistical analysis, rather than in everyday conversation.

Frequency of Use

The term is primarily used in written contexts, particularly in academic literature and technical articles related to genetics, biology, and statistics.

Example Sentences

1. The researchers focused their study on the additive variance present in the population's genetic data.

2. Исследователи сосредоточили своё внимание на аддитивной варьируемости, присутствующей в генетических данных популяции.

3. Understanding additive variance is crucial for breeding programs aimed at improving certain traits in crops.

4. Понимание аддитивной вариации имеет решающее значение для программ селекции, направленных на улучшение определённых черт в сельскохозяйственных культурах.

5. The scientists found that the additive variance could substantially influence the heritability of the trait.

6. Ученые обнаружили, что аддитивная вариация может существенно повлиять на наследуемость этого признака.

Idiomatic Expressions

While "additive variance" does not appear to be a commonly used element in idiomatic expressions, the concept of variance can be related to various phrases that convey the idea of change or difference. Here are some expressions featuring "variance" and related terms:

1. There is a wide variance in opinions amongst the team.

2. Существует значительная разница во мнениях среди команды.

3. The variance in results can often be attributed to external factors.

4. Разница в результатах часто может быть отнесена к внешним факторам.

5. High variance indicates greater risk in statistical analyses.

6. Высокая изменчивость указывает на больший риск в статистических анализах.

7. We must account for variance when developing the model.

8. Мы должны учитывать вариацию при разработке модели.

Etymology

The term "additive" comes from the Latin word "additivus," meaning 'that can be added.' The word "variance" is derived from the Latin "varians," which means 'varying,' and has been used in statistical contexts since the mid-20th century to denote variability or differences.

Synonyms and Antonyms

Synonyms: - Genetic variance - Heritable variance - Component variance

Antonyms: - Non-additive variance - Fixed variance

In summary, "additive variance" is a technical term closely tied to the fields of genetics and statistics. Its usage is largely confined to written and academic contexts, with variations relevant in discussions of genetic heritability and statistical analysis.
