You measure narrow-sense heritability for three traits and find that it is 0.1 for trait A, 0.5 for trait B, and 0.8 for trait C. Which of the following can you conclude from your data?

Question

Quizplus · Accepted Answer

Narrow-sense heritability estimates the proportion of the phenotypic variance that can be attributed to additive genetic variance. A higher heritability (closer to 1) means a greater proportion of the trait's variation is due to additive genetic factors, which implies that a parent-offspring regression for trait C (with the highest heritability of 0.8) will have the highest slope among the traits, indicating a strong genetic influence on the trait's variation.
