For example, say a man 175 cm tall marriesa woman 165 cm tall, and both
are from a Chinese population with a populationmean of 170 cm for men and
160 cm for women. We can predict the height of theirchildren, assuming the
heritability is 65 percent for men and 60 percent forwomen in this
population. For a son, the expected height difference from thepopulation
mean is: 0.65 x [(175 - 170) + (165 - 160)] / 2, which equals 3.25cm; 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 173.2cm,
and of a daughter 160 + 3, or 163 cm. On the other hand,
environmentaleffects 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 twosiblings (brothers and sisters); the actual
observed height may be different.

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。 | d****o 发帖数: 32610 | 2 肘子自己抄也就罢了

What is the benefit of sneezing in general? The easy answer is that the
thing tickling your nose might be a bad thing (like a virus, bacteria or
pollen), and sneezing forces it out. The problem is that most adults sneeze
mostly through their mouth, and so sneezing won’t force anything out of the
nose. This is in contrast to most animals, who sneeze largely through their
nose (watch your dog or cat next time). So I think that sneezing really
serves little purpose to humans (little kids might be an exception to this).
I think that sneezing is important to animals that rely heavily on the
sense of smell, but that in us it is just an annoying "holdover" of
evolution. But that is just my opinion

打喷嚏有什么用呢?由于喷嚏是因为有外来物刺激鼻腔粘膜产生的,人们马上会想
到,打喷嚏是为了把这些有害物质清除出去,同时也能清洁鼻腔,免得它被外来物堵塞
,让鼻腔更好地发挥过滤空气的作用。问题是,成年人在打喷嚏时通常是张大嘴打的,
这样的话就不容易把鼻腔里的脏物排出去,对鼻腔的清洁作用很有限。不像大多数哺乳
动物,它们是闭着嘴打喷嚏的,能有效地清洁鼻腔。多数哺乳动物的嗅觉非常敏感,它
们赖以生存,喷嚏清洁鼻腔的作用就非常重要。而人类的生存更多地靠视觉,嗅觉已大
大退化了,喷嚏的好处也就没那么明显。对人类来说,喷嚏可能只是进化的遗迹,没有
太大的益处。 | n*****s 发帖数: 6495 | | g****2 发帖数: 1 | 5 菊花那时还在新华社做不卖身的妓者呢。
