Heritability - Meaning, Definition & English Examples
Heritability is the proportion of variation in a trait among individuals that can be attributed to genetic differences. It helps explain how traits are passed down in populations.
Definition:
The proportion of observable differences in traits among individuals due to genetic differences.
Synonyms:
inheritance, genetic transmission, hereditary pattern
Part of Speech:
noun
Antonyms:
nonheritability, environmental influence
Common Collocations:
high heritability, low heritability, heritability estimate, genetic heritability
Derivatives:
heritable, inherit
Usage Tips:
Use "heritability" when discussing the genetic contribution to traits in populations, not individuals.
Common Phrases:
"heritability index, " "heritability coefficient, " "narrow-sense heritability"
Etymology:
Derived from "heritable," from Old French *heriter*, meaning "to inherit," and the suffix "-ity."
Examples:
- 1. The heritability of height is often studied in genetics.
- 2. Scientists debate the heritability of intelligence across different environments.
- 3. High heritability suggests genes strongly influence a trait’s variation.
- 4. Heritability estimates help distinguish genetic from environmental effects.
