Distinguish between broad sense heritability and narrow sense heritability, and explain how either or both of these measures can be used to inform those using artificial selection
What will be an ideal response?
Narrow sense heritability refers to the proportion of total phenotypic variation that can be attributed to the additive effects of genes, whereas broad sense heritability is the proportion of total phenotypic variation caused by all genetic effects. However, narrow sense heritability is the only component of variation that natural selection can act on and, thus, provides more accurate selection information.
