有序的四分体数据提供了染色单体干扰、交叉干扰和着丝粒位置的信息。在本文中,我们证明无染色单体干涉的假设对多位点有序四分体概率施加了一定的约束。假设没有染色单体干扰,这些约束可以用于一般交叉过程下的标记排序。我们还推导了一类交叉干涉模型下的多位点四分体概率,即卡方模型。最后,我们比较了卡方模型下的着丝点映射函数与文献中提出的映射函数。本文的结果可应用于排序遗传标记和利用多位点有序四分体数据绘制着丝粒。
Ordered tetrad data yield information on chromatid interference, chiasma interference, and centromere locations. In this article, we show that the assumption of no chromatid interference imposes certain constraints on multilocus ordered tetrad probabilities. Assuming no chromatid interference, these constraints can be used to order markers under general chiasma processes. We also derive multilocus tetrad probabilities under a class of chiasma interference models, the chi-square models. Finally, we compare centromere map functions under the chi-square models with map functions proposed in the literature. Results in this article can be applied to order genetic markers and map centromeres using multilocus ordered tetrad data.
