Interestingly, according to Health Day News:
Tall or short, it's long been known that genes account for much of a person's height. Now, scientists have found that short people actually might be missing copies of certain genes, which can leave them significantly smaller than average.
Studying DNA from more than 11,000 children and adults, an international team of researchers learned that those of short stature -- defined roughly as falling into the shortest 2.5 percent of their peer group -- had an excess number of rare deletions, or missing copies, of specific genes. Thus far, most research into genes and height has centered on identifying variations in common genes instead of an absence of others, study author Dr. Joel Hirschhorn said. READ MORE
