11、可能原因入手，推出每种可能情况下M果蝇的基因型，进而设计实验步骤和预测实验结果。分析题干可知，三种可能情况下，M果蝇基因型分别为XRY、XrY、XrO。因此，本实验可以用M果蝇与正常白眼雌果蝇(XrXr)杂交，统计子代果蝇的眼色。第一种情况下，XRY与XrXr杂交，子代雌性果蝇全部为红眼，雄性果蝇全部为白眼；第二种情况下XrY与XrXr杂交，子代全部是白眼；第三种情况下，由题干所给图示可知，XrO不育，因此与XrXr杂交，没有子代产生。,1,2,3,4,5,6,7,8,9,10,11,12,13,15,16,17,14,1,2,3,4,5,6,7,8,9,10,11,12,13,15,16,17,秋水仙素诱导染色体数目加倍,植物体细胞杂交,AABBCD,14,42,无同源染色体配对,染色体结构变异,14,1,2,3,4,5,6,7,8,9,10,11,12,13,15,16,17,14,1,2,3,4,5,6,7,8,9,10,11,12,13,15,16,17,14,
