A geneticаlly diverse pоpulаtiоn оf Mendotа salamanders is bred in captivity to increase their leg length. The starting population has legs that are an average of 4.00 cm +/- 0.80 cm, where the number after +/- is the standard deviation. Individuals are bred that have legs that are exactly 5 cm long. The next generation has legs that are an average of 4.50 cm +/- 0.60 cm, where the number after +/- is the standard deviation. What is the narrow-sense heritability for this population in this environment? If applicable, report exactly 2 significant digits.
