       Many parents who welcome the idea of turning off the TV and spending more time with the family are still worried that without TV they would be too often on call as entertainers（娱乐者） for their children．They remember thinking up all sorts of things to do when they were children．But their own children seem different, less good at finding things to pass the time, somehow．When there’s nothing to do, these parents notice regretfully that their children seem unable to come up with anything to do besides turning on the TV．

One father, for example, says, “When I was young, we were always thinking up things to do, projects and games．We certainly never complained in an angry way to our parents, ‘I have nothing to do”．He compares this with his own children today: “They are simply lazy．If someone doesn’t play with them, they’ll happily sit there watching TV all day．”

There is one word for this father’s disappointment: unfair．It is as if he were disappointed in them for not reading Greek though they have never studied the language．He feels his children’s lack of inventiveness a great pity, as if the ability to play were something born that his children are missing．In fact, the tendency（倾向） to play is built into the human species, but the actual ability to play—to imagine, to invent in a playful way, and the ability to gain satisfaction after successful effort from it—these are skills that have to be learned and developed．

Such disappointment, however, is not only unjust, it is also destructive（毁灭性的）．Sensing their parents’ disappointment, children come to believe that they are, indeed, lacking something, and that this makes them less worthy of admiration and respect．Giving children the chance to develop new things to enjoy themselves, to enrich their knowledge and experience and discover the pleasure of doing things on their own is, on the other hand, a way to help children develop a confident（自信）feeling about themselves as able and interesting people．

某生物科技小组对一玉米农田进行实地调查，发现正常玉米的基因型为A_B_，其顶部开雄花，下部开雌花；基因型为aaB_的玉米不能开出雌花而成雄株；基因型为A_bb或aabb的玉米的顶端长出的是雌花而成为雌株(两对基因位于两对同源染色体上)。请你运用所学知识协助该小组解决一些实际问题。

玉米的纯合体雄株和雌株在育种中有重要的应用价值，在杂交育种时可免除人工去雄的麻烦。为了确保纯合体雄株和雌株的杂交后代都是正常植株，那么选育出的符合生产要求的纯合体雄株和雌株基因型分别为______。
