For example, say a man 175 cm tall marries a woman 165 cm tall, and both are
from a Chinese population with a population mean of 170 cm for men and 160
cm for women. We can predict the height of their children, assuming the
heritability is 65 percent for men and 60 percent for women in this
population. For a son, the expected height difference from the population
mean is: 0.65 x [(175 - 170) + (165 - 160)] / 2, which equals 3.25 cm; for a
daughter, the difference is 0.6 x [(175 - 170) + (165 - 160)] / 2, which
equals 3 cm. Thus, the expected height of a son is 170 + 3.2, or 173.2 cm,
and of a daughter 160 + 3, or 163 cm. On the other hand, environmental
effects can add 1.75 cm to a son's height: 0.35 x [(175 - 170) + (165 - 160)
] / 2, and 2 cm to a daughter's: 0.4 x [(175 - 170) + (165 - 160)] / 2. Of
course, these predictions only reflect the mean expected height for each of
the two siblings (brothers and sisters); the actual observed height may be
different.
The most important nutrient for final height is protein in childhood.
Minerals, in particular calcium, and vitamins A and D also influence height.
假定一个身高1.75米的中国男子和一个身高1.65米的中国女子结婚，如果生的是儿子，
我们可以预测遗传因素会让他比平均身高高出0.65 x [(175 - 170) + (165 - 160)] /
2 = 3.25厘米，如果生的是女儿的话，则是0.6 x [(175 - 170) + (165 - 160)] / 2
= 3厘米。环境因素有可能会让儿子再高出0.35 x [(175 - 170) + (165 - 160)] / 2
= 1.75厘米，女儿高出0.4 x [(175 - 170) + (165 - 160)] / 2 =2厘米。当然这只
是平均值，实际情形会有所差异。如果加强营养，则有可能让子女长得比父母高。影响
身高的最重要的营养素是蛋白质，其次是钙等矿物质和维生素D、A。
