八年级生物下册的期中考试快开始了,整理好复习提纲有助于我们复习的效率。接下来是读文网小编为大家带来的八年级生物下册期中考试复习提纲,供大家参考。
生物的遗传和变异
遗传:是指亲子间的相似性。
变异:是指子代和亲代个体间的差异。
第一节 基因控制生物的性状
1 生物的性状:生物的形态结构特征、生理特征、行为方式.
2 相对性状:同一种生物同一性状的不同表现形式。
3 基因控制生物的性状。例:转基因超级鼠和小鼠。
4 生物遗传下来的是基因而不是性状。
第二节 基因在亲子代间的传递
1.基因:是染色体上具有控制生物性状的DNA 片段。
2.DNA:是主要的遗传物质,呈双螺旋结构。
3.染色体 :细胞核内能被碱性染料染成深色的物质。
4.基因经精子或卵细胞传递。精子和卵细胞是基因在亲子间传递的“桥梁”。
5、每一种生物细胞内的染色体的形态和数目都是一定的。
6、在生物的体细胞中染色体是成对存在的,基因也是成对存在的,分别位于成对的染色体上。
7、在形成精子或卵细胞的细胞分裂中,染色体都要减少一半,且单条存在。
第三节 基因的显性和隐性
1.相对性状有显性性状和隐性性状。杂交一代中表现的是显性性状。
2. 隐性性状基因组成为:dd 显性性状基因组称为:DD或 Dd
3.我国婚姻法规定:直系血亲和三代以内的旁系血亲之间禁止结婚.
4.如果一个家族中曾经有过某种遗传病,或是携带有致病基因,其后代携带该致病基因的可能性就大.如果有血缘关系的后代之间再婚配生育,这种病的机会就会增加.
Aa Aa
A a A a
AA Aa Aa aa
例.某班同学对人群中双眼皮和单眼皮的遗传情况进行了抽样调查,其调查统计结果如下表:请回答下列问题:(1)从 第 一 组 调查的结果可推测出控制 双眼 皮 性状的基因是隐性基因。
(2)如果控制显性性状的基因用A表示,控制隐性性状的基因用a表示,第3组所调查的家庭中,其母亲的基因组合是 aa ,其父亲的基因组合是 AA,Aa 。
(3)如果第2组某家庭中的母亲做了双眼皮手术后,再生一个孩子是双眼皮的可能是 0
原因是 这种变化是环境因素影响的,遗传物质没有发生改变,不会遗传给后代 。
(4)父母为双眼皮,而女儿为单眼皮,此现象称为 变异 ,这对夫妇若再生一个孩子,孩子眼睑的性状是双眼皮或单眼皮,是单眼皮的可能性为 25% 。
#FormatTableID_0# #FormatImgID_0#
第四节 人的性别遗传
1.每个正常人的体细胞中都有23对染色体.(男:44常+XY 女:44常+XX)
2.其中22对男女都一样,叫常染色体,有一对男女不一样,叫性染色体.男性为XY,女性为XX.
3.生男生女机会均等,为1:1
例1、如图表示人的生殖发育过程中染色体数目的变化,据图回答:
(1)a、b分别表示父母的体细胞他们的染色体数均为46 条。
(2)A表示父母分别产生生殖细胞的过程,生殖细胞c、d分别 精子和 卵细胞,他们的染色体均为 23 条, 比a、b 减少了 一半 。
(3)B过程为 受精过程 ,形成的e细胞叫 受精卵 ,染色体数为 23 对f细胞是女儿的体细胞,其染色体为 46 条 。体细胞中的每一对染色体都是一条来自 父方 ,一条来自 母方 .
第五节生物的变异
1.生物性状的 变异 是普遍存在的。变异首先决定于 遗传物质基础 的不同,其次与环境也有关系。因此有可遗传的变异和不遗传的变异。
2.人类应用遗传变异原理培育新品种例子:人工选择、杂交育种、太空育种(基因突变)
例1.培养试管婴儿的过程,正确的方式是
A.体内受精→胚胎移植→试管中发育 B.体内受精→试管中发育→胚胎移植→母体中发育
C.体外受精→试管中发育D 体外受精 → 试管中发育 → 胚胎移植 → 母体中发育
3.子女长得像父母是因为
A.父母把全部基因都传给了孩子 B.父母把所有的性状都传给了孩子
C.父母分别把部分基因传给了孩子 D.父母和孩子吃住在一起
4.牛的体细胞内有30对染色体,那么牛的生殖细胞和受精卵中的染色体数分别是
A.30条,30对 B.30对,30条 C.30条,30条 D.30对,30对
5.已知双眼皮和单眼皮是一对相对性状,其中双眼皮是显性性状,用D表示,单眼皮是隐性性状,用d表示。有一对夫妇均为单眼皮,那么,他们后代基因型为DD子女的概率是
A.100℅ B.50℅ C.25℅ D. 0℅
6.我国学者童第周等人从蝾螈内脏细胞中提取DNA注入到金鱼的受精卵中,结果约有1℅的小金鱼在口后长有类似有尾两栖类的平衡器。这个实验证明DNA
A.分子结构相对稳定 B.能够自我复制 C.能控制性状 D.能产生可遗传变异
7.白化病的基因是隐性基因(h)小明的父母都表现正常,而小明是白化病人,则小明父母的基因组成分别是
A.hh和hh B.Hh和hh C.Hh和Hh D.HH和hh
8.下列几种变异中,不能遗传的变异是
A.人类的皮肤:黑、黄、白 B.玉米粒的黄、白、红
C.A、O、B血型 D.生长在遮阴处的小麦秆细、穗小
9.禁止近亲结婚的目的是
A.防止遗传病的发生 B.防止遗传病的传播
C.减小遗传病发生的概率 D.缩小遗传病发生的范围
10、如图所示,通过转基因技术培养的老鼠比普通老鼠大许多,请回答:(6分)
⑴ 在转基因鼠研究中,被研究的性状是 鼠个体的大小 ,控制这个性状的基因是 大鼠生长激素基因。
⑵ 在生物代代繁衍的过程中,传下去的是 基因 ,而不是 性状
⑶ 性状与基因之间的关系是 基因 决定 性状 。

It was another day to jump rope in gym class. Lynn and Mike turned the long rope in big, slow circles. The whole class hurried to get in line to wait for their turn to jump. Millie stood at the back of the line and frowned.
Nick went first. He watched the rope and ran in at just the right time. Everyone counted. He made it all the way to 30 jumps. One after another, the kids watched the rope, ran in, and jumped. Then it was Millie’s turn. She watched the rope go around and around, but she didn’t move. She felt like everyone was looking at her.
Millie’s friends cheered. “Go, Millie, go!”
Millie’s face turned red. At last, she gave it a try, but she failed.
The truth was that Millie had been jumping rope at home every day. With a short rope, she could jump 100 times without missing. She just didn’t know how to run in and start jumping with a long rope. Since she was the only kid on her street, there was no one to help
turn the long rope.
Just then, Ms Miles, the gym teacher, brought out a bunch of short jump ropes.
"Let's see how long each one of you can jump without missing," she said as she gave each student a short rope, "Ready, set. Go!"
Millie smiled for the first time ever in gym class. As she jumped, she sang rhymes quietly to herself.
After a while, Millie realized that everyone was cheering, "Go, Millie, go!"
She was the only one still jumping rope! The surprise almost made her miss a step, but she kept going. When at last she was too tired to go on, she stopped. The whole class cheered. Everyone was looking at her and smiling. Millie smiled back!
36. Which word is the opposite of the underlined word frowned?
A. Sat. B. Hid. C. Smiled D. Cried
37. What problem did Millie have at the beginning of the story?
A. She didn't have any friends in her class.
B. She felt sad because Nick made fun of her.

39. Which sentence can be put in the empty?
A. The class decided to play baseball.
B. Millie was the last one still jumping rope.
C. Nick won the rope-jumping contest.
D. Millie tried to hide in the back of the line.

C
"Listen carefully to what I say," the time traveler said, "I shall tell you something that you will not agree."
"Why will we not agree?" I asked.
"Because the science and mathematics you know are not correct," he said. "You believe there are only three dimen sions(三维空间)-length, breadth(宽) and thickness."
"There is nothing to argue with that, " the youngest member of our little group said.
"Exactly!" the time traveler answered, "But there is also a fourth dimension - time."
"We all know about time, " another member of the group said. "Time passed."
英语试题 第4页 (共8页)
"I do not agree," the time traveler said, "Length, breadth and thickness do not pass. They stay in the same place in space. We move about them. I can prove that time is the same. It does not pass. We move in time the same way that we move in breadth, length and thickness."
None of us believed the time traveler, and we argued with him for many hours.
"If we could travel back in time," the scientist said, "We could do things to change the future."
"If we could travel forward in time," the doctor(博士) said, "we could do things that change our present."
The time traveler smiled, "It is clear," he said, "that there is only one way I can show you that I am right. We must do an experiment. Please wait here."
