Definition
Heritability does indicat the degree to which a trait is genetically determined
An individual does not have heritability
Heritability always refers to populations
There is no universal heritability for a trait
Does not provide infor about differences between populations for a particular trait
Even if heritability is high, environmental influences is important
Natural selection can occur only if there is genetic variation for a trait among the individuals of a population |
