某二倍体作物宽叶(M)对窄叶(m)为显性,高茎(H)对矮茎(h)为显性,红花(R)对白花(r)为显性.基因M、m与基因R、r在2号染色体上,基因H、h在4号染色体上.

(1)为获得宽叶抗倒伏(矮茎)的植株,育种学家用基因型MMHH植株为母本和mmhh的植株为父本杂交获得F1,F1自交获得F2,F2宽叶抗倒伏的植株中能稳定遗传的比例为____ .要在较短时间内获得能稳定遗传的宽叶抗倒伏(矮茎)的植株最好采用的育种方法为____ 

(2)在F1中发现有一株三体变异植株,其基因组成为MmmHh,此变异形成的最可能原因是____ 

(3)基因M、R编码各自蛋白质前3个氨基酸的DNA序列如图所示,起始密码子均为AUG.若基因M的b链中箭头所指碱基C突变为A,其对应的密码子由____ 变为____ .育种学家发现一白化植株,检测发现,在正常植株体细胞中的一种由146个氨基酸组成的多肽链在白化植株体内仅含45个氨基酸.由此可推测此突变是正常mRNA第____ 位密码子变为终止密码子所致.

(4)科学家研究发现,R基因编码的R蛋白具抗病功能.为获得抗病水稻,科学家尝试将R基因转入水稻体内,使水稻细胞表达R蛋白.分子杂交技术可用于基因检测,其基本过程是用标记的DNA单链探针与____ 进行杂交.若要检测R基因是否转录,则基因探针序列为____ ;为制备大量探针,可利用____ 技术.
