If genes strongly influence average levels of a trait…
““If genes strongly influence average levels of a trait, that trait is strongly inherited. If genes strongly influence the extent of variability around that average level, that trait has high heritability.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Heritability measures how much genetic differences explain variation in a trait across a population, not how much a trait is passed from parent to child.
In simple terms: Genes explain population variation, not individual inheritance.
Key Takeaway
