染色單體干擾（chromatid interference)——在細胞減數分裂過程中，兩非姊妹染色單體間發生一個交換後影響相同兩染色單體間發生第二次交換的現象。
English definition:
A situation in which the occurrence of a crossover between any two nonsister chromatids can be shown to affect the probability of those chromatids being involved in other crossovers in the same meiosis.
