根据短文内容,完成表格。

    As you know, homework is a big part of going to school. Luckily, here are several suggestions for you to make homework easy.

    Make a homework plan

    Most middle school students have two or three hours of homework a night. If it is a heavy homework day, you may need to spend even more time. It is a good idea to come up with some kind of homework schedule(进度表), especially if you are going to do sports or other activities after school.

    Watch where you work

    A bedroom, study or any room where you can get away from noise is good for you to do your homework. But don't study on your comfortable bed, or you might fall asleep there.

    Take a break

    Most people's attention (注意力) don't last very long, so take some breaks while doing your homework. Sitting for too long without relaxing will make you less productive(多产的) than if you stop to take a break regularly. Taking a 15-minute break every hour is a good way for most people.

    Get help when you need it

    Sometimes even though you are listening carefully in class, some subjects seem too hard. The first person to ask for help is your teacher. He or she may be able to work with you before or after school and explain things more clearly. Your classmates may also be able to give you a hand. However, this might not give you the results you want. Lots of people understand something well but are not able to explain it.

某禾本科植物(2n=14)开两性花,可自花传粉.研究者发现有雄性不育植株(即雄蕊发育异常不能产生有功能的花粉,但雌蕊发育正常能接受正常花粉而受精结实),欲选育并用于杂交育种.请回答下列问题:

(1)雄性不育与可育是一对相对性状.若用该相对性状验证孟德尔分离定律,该相对性状应满足2个条件:条件1是所选相对性状____ 、条件2是所选相对性状____ .

(2)在杂交育种中,雄性不育植株应用优势是____ .

(3)为在开花前即可区分雄性不育植株和可育植株,育种工作者培育出一个三体新品种.相应基因与染色体的关系如图(基因M控制可育,m控制雄性不育;基因R控制种子为茶褐色,r控制黄色).  

①带有易位片段的染色体不能参与联会,因而该三体新品种的细胞在减数分裂时可形成____ 个正常的四分体;减数第一次分裂后期联会的两条同源染色体彼此分离,分别移向细胞两极,而带有易位片段的染色体随机移向一极.故理论上,含有8条染色体的雄配子占全部雄配子的比例为____ ,经研究发现这样的雄配子不能与雌配子结合.

②此品种植株自交,所结的黄色种子占70%且发育成的植株均为雄性不育,其余为茶褐色种子,发育成的植株可育.结果说明三体植株产生的含有8条染色体和含有7条染色体的可育雌配子的比例是____ ,这可能与带有易位片段的染色体在减数分裂时的丢失有关.

③若欲利用此品种植株自交后代作为杂交育种的材料,可选择____ 色的种子留种;若欲继续获得新一代的雄性不育植株,可选择____ 色的种子种植后进行自交.
