Limitations of heritability

Heritability does not indicate the degree to which a characteristic is genetically determined. 

An individual does not have heritability. 

There is no universal heritability for a characteristic. 

Even when heritability is high, environmental factors can influence a characteristic. 

Heritabilities indicate nothing about the nature of population differences in a characteristic.
