45、(18分)芦笋是常见的雌雄异株植物之一，为XY型性别决定，雌株的性染色体为XX，雄株的性染色体为XY，其染色体数目为2N=20。野生型芦笋叶窄，在野生种群中，一株雌芦笋的一条染色体上某基因发生了突变，由窄叶突变成为阔叶，用该植株与野生型雄株杂交，F1雌雄植株中均有窄叶，也有阔叶。(基因用字母B、b表示)
⑴ 在窄叶和阔叶这对相对性状中，显性性状是 。
⑵ 上述杂交实验的结果能否确定阔叶基因在X染色体上还是在常染色上？ 。
用文字简要说明推断过程。
⑶ 假如控制窄叶和阔叶的基因位于X染色体上。由于雄株的产量高于雌株，某园艺场需要通过一次杂交育种培育出一批在幼苗时期就能识别出雄性的植株，请你设计一个简单实用的杂交方案。(提供的植株有阔叶雌雄株、窄叶雌雄株，要求用遗传图解表示杂交方案)
⑷ 现只给你提供芦笋雄株，请设计一套育种方法，从理论上保证得到的子代全是雄株，写出简要过程。(不直接采用组织培养法)
