Heritability

Heritability - the degree to which the variability of a particular trait in a particular population is a result of genetic influence among those organisms. 

A heritability coefficient of 1.00 means all of the variability in a particular trait is due to genetics. A heritability coefficient of 0.00 means none of the variability is due to genetics. 

Watch Out!
Heredity is only a useful number on a population level - it does not allow us to predict anything about a particular person 

Some traits, like height and intelligence, are more heritable than others, like personality or school achievement. 

Practice: Heritability
We know from many studies that the heritability of intelligence is 57-73%. If we know the intelligence of a person's biological parents, we know: 

A) that the person's IQ score will be the average of the two parents' IQ scores, with a margin of error somewhere between 57% and 73% 

B) that the person's IQ score will be in the range of 57%-73% higher or lower than the average of their parents' IQ scores 

C) that a person with high IQ parents will have a higher IQ than a person with low IQ parents 

D) that, in general, people with high IQs have high IQ parents
