人们早就知道，染色体的一个部分的交叉会降低同一染色体其他部分进一步交叉的可能性。最近，Haldane (1931) 证明，减数分裂第一次分裂时二价体中交叉形成的频率分布也表明发生了干扰。然而，已假定一种二价的交换与同一核的其他二价的交换无关。最近的工作使人们对这一假设的有效性产生了怀疑。
It has long been known that crossing over in one section of a chromosome reduces the probability of further crossing over in other sections of that same chromosome. More recently it has been demonstrated by Haldane (1931) that the frequency distributions of chiasma formation in bivalents at the first division of meiosis also indicate that interference occurs. It has, however, been assumed that crossing over in one bivalent is independent of crossing over in other bivalents of the same nucleus. Recent work has rendered doubtful the validity of this assumption.
