A breeder wishes to estimate narrow sense heritability for adult weight in a population of Turkeys. The mean weight of the
parental population was 18 pounds. Turkeys with a mean weight of 26 pounds were used to produce the next generation,
which had a mean weight of 20 pounds. What is the narrow-sense heritability for these Turkeys. Would this estimate be
accurate if offspring and parents received a different diet? Explain.
