Interestingly it has been recently shown that 70% of the variation in height is accounted for by ONE gene held on the X chromosome. Which explains why XXX or XXY people are taller than average.
Sorry for the vagueness of the above: this is from memory from a report I read in New Scientist a few weeks ago. If someone has better details please post them, obviously its was a great surprise to find that one gene accounted for so much variation.
