设${\left(2-x\right)}^6=a_0+a_{1}x+a_{2}x+\cdots +a_{6}x$,则$\left|a_1\right|+\left|a_2\right|+\cdots +\left|a_6\right|$的值是 （    ）

孟德尔获得成功的原因之一是因为正确选择了豌豆作为实验材料．

（1）豌豆（2n=14）的果皮黄豆荚与绿豆荚，红花与白花为自由组合的两对相对性状．甲豌豆为绿豆荚红花、乙豌豆为黄豆荚白花，且均为纯合体，据此回答下列问题：

①若用乙豌豆的花粉为甲豌豆授粉进行人工杂交，需要对甲豌豆花进行的处理包括____ ．如果甲植株上结的全部是绿豆荚，将其内的种子种下，发育成的植株均开红花，由此可判断出的显隐关系是____ ．

②设甲、乙杂交为亲本，花色将在____ 代植株上出现性状分离．F₂代植株中，重组性状（亲本没有的性状组合）占____ ．

③若对该植物进行基因组测序，需要测定____ 条染色体的基因序列．

（2）豌豆的某一相对性状共有5种不同的表现型，该性状受三对独立的等位基因控制，其中A基因控制表现型Ⅱ，B基因控制表现型Ⅲ，D基因控制表现型Ⅳ，如表所示：

①已知三种显性基因之间存在着相互抑制的关系，根据表中信息分析，三者之间的抑制关系为____ ．

②表现型V的植株共有____ 种基因型，其中AaBbDd的植株自交，后代中表现型为Ⅲ的个体占____ ．

③现有一株表现型Ⅱ的植株，若用自交的方法来鉴别其基因型，其中有____ 等三种基因型的植株不能根据子代的表现型及其分离比例进行判断．

利用表现型Ⅰ对其进行测交，____ （填“能”或“不能”）区分这三种基因型，因为____ ．

④基因型为aaBbDd与AAbbDd的植株杂交，请用遗传图解表示出杂交结果（要求注明亲、子代的基因型、表现型，以及子代的性状分离比）．

Lizzie-s diary from Antarctica (南极洲)

Day 3: Tuesday   December 2

    We planned to go to Rothera that morning. We'd be staying there for the next two weeks. Because Antarctica is the windiest place on earth, sometimes you can't fly at all.

    We had a nervous wait over breakfast to find out if we'd be leaving that day. People have to stay in Stanley for weeks while the pilots wait for good weather.

    It turned clear at 9:30 and we took off at 10:30 on a little red plane called a Dash-7. But even when we were in the air, there was still a chance we wouldn't be able to fly the whole day.

Day 4: Wednesday   December 3

    After waking up in the Antarctic for the first time today I can understand why everybody who comes here falls in love with the place. It is really beautiful.

    We're staying at Rothera Survey base with mountains of ice all around. It s about minus 2⁰C today, which for me is very cold, but the regulars(常客) here are often seen walking around in T-shirts !

Day 5: Thursday  December 4

    I woke up to another beautiful sunny day here in the Antarctic. I'm told it's a bit colder today, about minus 5℃ , but it's not very windy so it feels warmer. Those of us who are new to the bas have to do a spccial training course before we're allowed to go off base to other stations or to go snowboarding over the nearby hill.

Day 7: Saturday  December 6

    Not a cloud in the sky and it's warm enough to sit outside (in a jacket).

    The most amazing thing about this place is how the scenery (风景) changes every day. At first I thought I was going mad. I'd step outside in the morning and think, "I'm sure that big mountain of ice wasn't there yesterday." It's because the sea ice is always moving—slowly thankfully !
