Quantitative genetics - What exactly is heritability?


Three possible ways to estimate the heritability of a real character:

• One method is to cross two pure lines. (This is mainly of interest in applied genetics, where the problem might be to breed a new variety of crops; it has little interest in evolutionary biology.)

• Another method is to measure the correlation between relatives.

• Finally, we can observe the response to artificial selection.
