Past attempts to obtain values for meiotic parameters relating to hybrid DNA formation and the correction of mismatched bases in hybrid DNA have not given unique solutions unless various simplifying assumptions were made. A method is given for identifying correct sets of solutions after calculating the frequency of hybrid DNA formation at a heterozygous site and using the fact that closely linked sites within a locus have very similar hybrid DNA formation frequencies. The method is illustrated with simulated data and Sordaria fimicola data; it can also show up incorrect assumptions in analysis. A method is suggested for assessing the importance of double-strand gaps in producing conversions.
过去尝试获取与杂种DNA形成以及杂种DNA中错配碱基校正相关的减数分裂参数值时,除非做出各种简化假设,否则无法得到唯一解。本文给出了一种方法,该方法先计算杂合位点处杂种DNA形成的频率,并利用基因座内紧密连锁位点具有非常相似的杂种DNA形成频率这一事实,进而识别出正确的解集。文中用模拟数据和粪壳菌数据对该方法进行了说明;它还能揭示分析中不正确的假设。本文还提出了一种评估双链缺口在产生转换过程中的重要性的方法。
