A quantitative model is proposed for the expected degree of relationship between copies of a family of transposable elements in a finite population of hosts. Special cases of the model (in which the process of homogenization of element copies either is or is not limited by transposition rate) are presented and illustrated, using data on mobile sequences from different species. It is shown that transposition will be expected, in large populations, to result in only a rather distant relationship between transposable elements at different genomic sites. Possible inadequacies of the model are suggested and quantified.
提出了一个定量模型,用于描述有限宿主群体中转座元件家族各拷贝之间的预期关联程度。利用来自不同物种的移动序列数据,展示并说明了该模型的特殊情况(即元件拷贝的同质化过程受或不受转座率限制的情况)。结果表明,在大群体中,转座预计只会导致不同基因组位点的转座元件之间存在相当远的关联。文中还指出并量化了该模型可能存在的不足之处。
