玉米是我国第一大粮食作物．玉米腐霉茎腐病在我国广泛发生严重危害粮食生产安全相关研究具有重要的经济价值和社会意义． 1玉米对腐霉茎腐病表现出的抗病与感病为一对． 2观察发现玉米品种甲纯系对腐霉茎腐病表现为抗病品种乙纯系表现为感病． ①研究人员将品种甲与品种乙杂交得到F1再将F1自交得到F2．检测发现产生的F1全部为抗病产生的673株F2中626株为抗病47株为感病．F2中的抗病感病≈151因此可推知抗病与感病由染色体上的对基因控制． ②研究人员又对F2进行单株自交将每株收获的种子分别种植观察表现型．有的F2单株自交子代都为抗病有的F2单株自交子代都为感病有的F2单株自交子代既有抗病又有感病．若上述三种F2的比例为即可验证2①所得结论． 3进一步研究发现品种甲的抗病基因R1位于玉米1号染色体上．已知抗病玉米品种丙纯系的显性抗病基因Q也位于1号染色体上． ①在玉米1号染色体上的特定位置有分子标记如z263它在玉米的不同品系里的长度可能不同但起始和终止序列相同．类似的还有z459z319和z256．已知品种丙的Q基因与z263z459z319和z256紧密连锁不发生交叉互换．科研人员根据这几个分子标记的起始和终止序列设计分别以品种甲乙的基因组DNA为进行PCR扩增后电泳检测．下图所示实验结果初步说明R1与Q是填“相同”或“不同”基因判断依据是． ②科研人员将品种甲与品种丙杂交得到F1F1均表现为抗病．再将F1自交得到F2．F2出现感病植株直接验证3①的结论．推测F2出现感病植株的原因是只考虑R1和Q基因．
