What is narrowsense heritability Why do researchers estimate

What is narrow-sense heritability? Why do researchers estimate this metric (i.e., why is it important or relevant)?

Solution

Answer :-

The narrow sense heritability is defined as the ratio of additive genetic variation to the total phenotypic variation.

H*=Va/Vp

Narrow sense heritability is impoetant in quantitative genetics because it helps to predict how a trait woyld response to selection pressure.
