Explain why narrow-sense heritability is a more accurate indicator of responsiveness to selection than is broad-sense heritability
What will be an ideal response?
Narrow-sense heritability is defined in terms of additive genetic variance, meaning that each allele of each contributing gene has a phenotypic effect. Broad-sense heritability is based on genetic variance in general. Since selective breeding is based on phenotypes, insofar as additive genetic variance is a more precise reflection of genotype underlying phenotype, this measure will help in making better selective breeding decisions.
