Narrow-sense heritability for a trait can be obtained from a regression of midparent value on offspring value.

Question

Quizplus · Accepted Answer

This is correct. Narrow-sense heritability (h²) is typically estimated by regressing offspring values on midparent values and obtaining the slope of the line of best fit. This slope is an estimate of the additive genetic variance for the trait, which is used to calculate narrow-sense heritability as h² = (additive genetic variance) / (total phenotypic variance).
