Meanings in context

Article-grounded definition

the trait’s heritability.

y_2 - y_1 = \phi_{,zz}\,h^2 + O(h^4).

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.

\phi_{,zz}\,h^2 = \sqrt2\,\sigma_y

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.

R = h^2 S

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.

h^2

the trait’s heritability.

h^2 \times i \times V = 0.50 \times 0.01 \times 0.01 = 0.00005

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.
