链孢霉四分体分析连锁基因距离矫正的一种简便方法和计算数据的修正

A Simple Method to Correct Genetic Distance Between Linked Genes and a Correction of Calculating Data in Tetrad Analysis in Neurospora crassa

本文探讨一个在链孢霉四分体分析中连锁基因距离矫正的简便方法。并提出在计算交换值时,当遇到着丝粒在两基因中间的类型时,应该把基因与着丝粒之间发生的四线双交换类型分别计入两个单交换内。

The present paper is dealing with a simple method to correct the distance of linked genes in tetrad analysis in Neurospora crassa.It is suggested that the data of 4thread double crossing over should be added in two single crossing over respectively in centromere maping when calculating crossover value of the two genes locating across the centromere.
