Impossible Heritability Given Repeatability

Correct Answer: 0.40

From the notes: Repeatability is the upper limit of heritability. So if repeatability = 0.35, then heritability CANNOT be greater than 0.35.

Evaluation of Options

• 0.30 ≤ 0.35 → Possible ✔
• 0.05 ≤ 0.35 → Possible ✔
• 0.15 ≤ 0.35 → Possible ✔
• 0.40 > 0.35 → NOT possible ✔ (correct answer)

Rule

Heritability (h²) ≤ Repeatability (r) ≤ 1. If any given heritability value exceeds the repeatability value, it is impossible.
