classic genetics question (Gustavo A. Seluja)

Here is my educated guess: A father and mother contribute equally. So,
roughly 50% of the sons genetic endowment comes from the father. 

For the brothers, there are two shuffles to consider: One to make a
sperm cell and the other when the sperm and egg join. So, I say that the
father and son have more genetic material in common. 

One additional caveat: If you ask how much is commonly EXPRESSED, I
might come up with a different answer.
