Whatever the reason I am afraid no one knows, no matter how high the threshold increase, or increase the ultimate cost of development, that is the price to the cost of containing them.
The great development in genomics makes it possible to unveil the genetic basis of threshold and quantitative traits at molecular level.
基因组研究的飞速发展，使人们从分子水平上了解阈性状和数量性状的遗传机理成为可能。
