Most variation in the human genome is neutral, meaning that it arose not by natural selection but by processes like harmless mutations and the random shuffling of the genome between generations.
人类的大多数变异基因都是中性的，这意味着变异之所以被激发不是出于自然选择，而是由于产生了良性变异或染色体在复制时候发生了混乱。
Some of this variation (exactly how much is the subject of debate) is meaningless, or “neutral” — it has absolutely no effect.
而有些变异（究竟有多少变异是争论的焦点）其实是没什么意义的，或者可有可无——坦白讲根本就没用。
The space that has the white neutral light surface in customary mode is able to be changed dramatically due to the variation of light flow.
通常呈现白色的中性光表面，根据光流的变化能够作出显著的变化。
