Misreading Heritability

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

It is an error to read heritability as the degree to which a trait is fixed in an individual.

Show

Height is highly heritable, and average height still rose sharply within populations as nutrition improved.

Watch for

High heritability does not mean unchangeable, and low heritability does not mean easily changed.
