## Problem 296 — rank:314

**Title:** Origin of hereditary individuality

**Added binding assumptions (LaTeX):**

```latex
The regression coefficient $h$ is conditioned on reproducing parents and is not necessarily in $[0,1]$ or a population-wide heritability. For scalar $Z$, the exact transmission decomposition is $\Delta\bar Z=\Cov(W,Z)/\E W+\E[W(Z'-Z)]/\E W$, with the $W=0$ product defined as zero. Positive covariance alone can be outweighed by transmission deterioration. Use consistent parent/daughter weighting and distinguish shared-environment correlation from inherited composition.
