Heritability
Captions available
The idea
Heritability is the proportion of variation in a trait within a specific population that is attributable to genetic differences.
In practice
A heritability estimate of 0.50 for a trait means half the variation in that population traces to genetic variation.
Where people slip
Heritability is a statement about a population and its environment, and it changes when either changes.
