segregating

Siblings and dizygotic twins share only 50% of their segregating genes.

同胞胎和胞胎分享仅50%的基因。

Obviously this method has every limited application in most instances, because of the impossibility or impracticability of segregating specific items as coming from separate purchases.

由于要辨认存货不同购买来源的具体批是不现实的，很明显个别计价法的使用有很大的局限性。
