1. For a specific desirable trait in a breed of sheep, VP is 28.6, VC is 11, and VA is 7.2. What is its broad sense heritability?
2. Phenylketonuria (PKU) is extremely common in Ireland, affecting approximately 1 in 4500 live births. What is the frequency of PKU carriers?
3. Calculate the narrow sense heritability (h2) for the following data on a trait in turkeys:
VA = 11.0
VE = 94.4
VP = 114.2
VD = 13.8
