Height is (almost) genetic

Common sense tell us people's height is (almost) genetic. Recently, scientists from UK and USA identified a gene that controls height. Each copy of the "tall" allele adds 0.2 inch, so inheriting two copies makes you nearly 0.5 inch taller than if you inherit two copies of the "short" allele. Studies indicate 90% of height is genetic. Many more height-related genes are expected to be found quickly.
