Question
In a breeding experiment involving quantitative traits,
a breeder calculated the phenotypic variance (VP) as 40 and genotypic variance (VG) as 30. Based on these values, what is the correct estimate of broad-sense heritability and what does it imply about trait inheritance?Solution
Broad-sense heritability (H²) is calculated as: H² = VG / VP = 30 / 40 = 0.75 or 75%. This indicates that 75% of the phenotypic variance is due to genetic factors, implying high genetic control and suggesting that the trait is largely heritable, making selection more effective. Â
