“他们杀孩子、老师，也杀牧师、工人、工匠、小店老板、鞋匠……全是纯朴勤劳的普通市民”一句中“全是”一词强调了作者____的感情。

科学家选用萌发的普通甜椒的种子搭载“神舟”飞船，利用在微重力和宇宙射线等各种因素作用下生物易发生基因突变的原理进行育种．从太空返回后种植得到的植株中发现有一株个体果实明显变大．请你用原有的纯种小果实普通甜椒和新发现的大果实太空甜椒为实验材料，设计一个方案，以鉴别大果实太空甜椒这一性状的基因型（假设果实大小是一对相对性状，且由单基因（D，d）控制的完全显性遗传）．

①你的实验设计原理是遵循遗传的____规律．

②请你在下表中根据需要，完成实验设计方案，并预测实验结果和得出相应的结论（结果和结论要对应，否则不得分）．
