Genetics as it applies to evolution, molecular biology, and medical aspects.

Does anyone know how to calculate the narrow sense heretability given data values from the parent to offspring. Example, in my Evolutionary biology class the professor posed a question that a farmer wanted to grow larger pumpkins, therefore he only allowed the pumpkins weighing >= 9 kg to reproduce. The weights of the parental generation allowed to reproduce were: 9,9,9,9,9,12,15 kg with a mean of 10.28 kg. The offspring's weights were as follows: 10,9,8,8,9,10,10,7,12,10 kg with a mean of 9.3 kg. This is all the data that my professor provided, I have equations for narrow sense but I do not have one that allows for simple plugging into eqns, for instance I do not know what level of the variation for parents to offspring is due to genetic verses environmental causes. I would appreciate any insight into this problem.
