A group of eight non-Mendelian genes have been shown by recombination analysis to be linked into a linear structure or chromosome. Similar genetic maps of gene order and relative distances between genes have been constructed by two methods, one based on additivity of recombination frequencies, the other on frequency of reciprocal recombination with a postulated attachment point. The data indicate that the progeny are diploid for this linkage group, and that the strands are distributed in a precisely oriented manner at mitosis. Evidence is discussed in support of the view that this linkage group is located in chloroplast DNA.
通过重组分析已表明,一组八个非孟德尔基因被连锁成线性结构或染色体。通过两种方法构建了基因顺序和基因间相对距离的类似遗传图谱,一种基于重组频率的加性,另一种基于与假定附着点的相互重组频率。数据表明,该连锁群的后代是二倍体,并且在有丝分裂时链以精确的方向分布。讨论了支持该连锁群位于叶绿体DNA中的观点的证据。
