Abstract
According to the model of FOSS, LANDE, STAHL and STEINBERG, chiasma interference is a reflection of the requirement for crossovers to be separated by an organism-specific number of potential conversion events without associated crossovers. This model predicts that tetrads with close double crossovers should be enriched for conversion events that themselves are not associated with crossing over. We tested this prediction in Saccharomyces cerevisiae and found it to be unfulfilled.
摘要
根据FOSS、兰德、施塔尔和斯坦伯格的模型，交叉干涉是指交叉需要被特定生物体数量的潜在转换事件隔开且无相关交叉的一种反映。该模型预测，具有紧密双交叉的四分体应富含本身与交叉无关的转换事件。我们在酿酒酵母中测试了这一预测，发现它并未得到满足。
