It is not the case that Quantitative genetics legitimately partitions phenotypic variance into heritable and environmental components via heritability coefficients (h²).

Set your confidence on the premises below to see your aggregate.
Reasons For
1 perspective
Reason for
?
1.
h² is population-specific and environment-specific; same trait shows different h² values across contexts, undermining universal claims.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Gene-environment interactions and correlations mean variance components cannot be cleanly separated; h² obscures rather than clarifies causation.
?
How convincing is this?
Think about whether this reason is strong or weak
3.
h² describes statistical decomposition of variance, not biological mechanisms; it answers 'how much variation?' not 'how does inheritance work?'
?
How convincing is this?
Think about whether this reason is strong or weak
Reasons Against
1 perspective
Reason against
?
1.
h² successfully predicts response to selection in controlled breeding experiments across diverse organisms with high accuracy.
?
How convincing is this?
Think about whether this reason is strong or weak
2.
Partitioning variance into additive genetic and environmental components enables quantitative prediction of trait inheritance in populations.
?
How convincing is this?
Think about whether this reason is strong or weak
3.
h² provides operational utility for agriculture, medicine, and evolutionary biology despite philosophical limitations about causation.
?
How convincing is this?
Think about whether this reason is strong or weak
