父母高,儿女的身材往往较高,父母矮,儿女的个头也大多较矮。科学家将此现象归结于遗传因素的制约。但是,矮夫妻们也不必悲观,因为遗传因素的影响力最多只占60％,另外40％则由后天因素决定。只要养育方法科学,孩子的个头照样可以长高。 High parents, children tend to be tall, parents are dwarfed, and children are mostly short. Scientists attributed this phenomenon to genetic constraints. However, dwarf couples do not have to be pessimistic, because the influence of genetic factors is only up to 60%, while the other 40% is determined by acquired factors. As long as the parenting method of science, the child’s head can still grow taller.
