Narrow-sense heritability is a more useful measure than broad-sense heritability in agricultural selective breeding.

Question

Quizplus · Accepted Answer

Narrow-sense heritability is a measure of the proportion of variation in a trait that is attributable to genetic variation within a population. It is more useful in selective breeding because it specifically measures the ability of offspring to inherit traits from their parents, which is the key factor in successful breeding programs. In contrast, broad-sense heritability includes both genetic and environmental factors that contribute to trait variation, which can make it more difficult to isolate the genetic components that drive successful breeding outcomes.
