概率法及相对运动法对链孢霉的连锁遗传作图分析

Analysis of genetic map of N.crassa by probability method and relative motion method

针对遗传学教材关于链孢霉的连锁遗传分析中的三个问题:(1)两对等位基因是否连锁;(2)是否位于着丝粒同侧;(3)着丝粒与nic重组率、nic与ade间的重组率、着丝粒与ade间的重组率三者间不存在等式关系.对于(1)、(2)两个问题分别采用概率法给予解答,对于(3)运用相对运动的观点给了三者各自的计算方法及三者间等式关系,即着丝粒与nic重组率+nic与ade间重组率=着丝粒与ade间的重组率.

This article on the ＂genetics＂ materials on c N. crassa chain genetic analysis of three issues ： （ 1 ） whether two pairs of allele chain or not, （2） are they located in centromere of the same side, （3） reorganization rate among centromere and the nic and ade-rate are not existent equality. The two issues of （ 1 ） and （2）, we answered by probability method ,but as for （3） relative motion method of the three respective perspectives to the calculation method and three-equation, reorganization rate namely： centromere and nic ＋ ade and nic = centro- mere and ade.
