Question: Assume you are analyzing two laboratory populations of pure-breeding mice. One population has very long tails and the other has very short tails. You perform a cross between the two populations P(short)*P(long) to determine heritability of tail length. You measure the tail length and find the following variance: P(short) = 2cm^2, P(long) = 2cm^2, F1 = 5cm^2, Original (totaly phenotypic variance) = 6cm^2. What is the heritability of tail length? Please explain them in details.
