【题目】中国是世界上最大的茄子生产国,为培养优良的品种,育种工作者进行了大量的实践。请分析并回答:
(1)茄子晚开花(A)对早开花(a)为显性,果实颜色有深紫色(BB)、淡紫色(Bb)与白色(bb)之分,两对基因自由组合。选择基因型AABB与aabb的植株为亲本杂交,F1自交得到的F2中有 种表现型,其中晚开花深紫色果实的植株占 。
(2)青枯病是茄子主要病害,抗青枯病(T)对易感青枯病(t)为显性,基因T、t与控制开花期的基因A、a自由组合。若采用二倍体早开花、易感青枯病茄子(aatt)与四倍体晚开花、抗青枯病茄子(AAAATTTT)种子为育种材料,在短时间内培育出纯合的二倍体早开花、抗青枯病茄子,则主要步骤为:
①第一步:种植四倍体晚开花、抗青枯病茄子(AAAATTTT),取 ,获得基因型为AATT的子代;
②第二步:以基因型 的茄子为亲本杂交,得到F1(AaTt);
③第三步:种植F1, ,获得纯合二倍体,从中选出表现型为早开花、抗青枯病的茄子。此过程依据的主要遗传学原理是基因重组和 。
