雌雄配子体融合为( )个合子的过程即为受精

花粉母细胞经过减数分裂形成( )小孢子

植物的生殖方式主要有无性生殖、有性生殖()

减数分裂过程中,染色体只复制一次()

如果在f1代的性母细胞减数分裂时,有6%的细胞在连锁着的基因ab之间出现了交叉结,则表明在这6%的细胞中有总数的 的染色单体在a、b之间发生过 。所以这些f1代个体在配子形成将有 重组型, 亲本型。

基因之间的重组率不止限于邻近基因座间

同一对染色体上的三个基因位置测定时,用双交换型与亲本类型相比较,发现改变了位置的那一个基因一定是处在中间的基因

连锁基因的交换率可以代表基因在同一染色体上的相对位置,人们就可以根据基因彼此之间的交换率来确定他们在染色体上的相对位置

位于同一条染色体上全部的基因组成一个连锁群

1. 数量性状的基本遗传规律为: 1)f1的平均值介于 之间。 2)f2平均值与 接近。 3)f2的变异幅度比f1的变异幅度更 ,且f2的极端类型与 接近。

数量性状的遗传规律是f2的变异幅度比f1的变异幅度更大( )

一个纯系范围内性状也有差异,这种差异完全是由于环境条件的差异。()

数量性状研究的对象是群体,对于个体来说难以确定( )

杂种后代数量性状的变异及表型的分布呈正态分布,表型是连续的( )

简述母性影响与母性遗传的异同点

雄性不育的植物可以分为核型雄性不育、细胞质雄性不育和核质互作雄性不育三种类型。

拿恢复系植株花粉给雄性不育株授粉,产生的后代继续为雄性不育系( )

雄性不育系只表现为隐性形状( )

保持系植株依靠本系花粉结实,所以从保持系植株收获的种子依旧是保持系( )

拟显性是染色体发生缺失时显性基因得到表达的现象。

只有遗传物质的改变才能出现新的基因,形成新的基因型。( )

染色体结构的变异,可以分为缺失 、重位 、倒位、 易位。

缺失有三种形式,一种为顶端缺失、一种为中间缺失,还有一种为末端缺失( )

染色体片段倒转90度,造成染色体内的重新排列。

遗传物质在理论上应当具备连续性、 稳定性、自主性

蛋白质的合成是mrna 、trna、rrna协同作用的结果。

dan是由4种不同的核苷酸组成

核苷酸序列的不同表现为碱基的不同。

普通的花是由雄蕊、 雌蕊、花瓣、花萼组成

黄色花的色素组成只含内胡萝卜素( )

花色素合成的起始和终止完全由基因调控( )

可以利用杂交育种的方法改良花色。

不规则彩斑可以分为区分彩斑和混杂彩斑两种( )

染色体畸变断裂-融合-桥的循环作用、环形染色体、黏性染色体的形成都有可能造成花色不规则彩斑的出现。( )

花瓣不规则条纹和斑点的出现的其中一个原因为:控制色素形成的基因从等位基因的一种形式频繁的突变为另一种形式( )

小的环形染色体可能会在细胞分离时丢失,具双着丝点的大染色体可能会发生断裂造成彩斑的出现。( )

嵌合体依两种组织在“共同体”中所处的位置可以分为3种类型。

几乎所有的嵌合体都无法稳定的遗传传递下去( )

嵌合体是遗传上不同的两种植物的组织机械地共存于一个生长点的植物。( )

用无性繁殖方法一定可以得到接穗类型、砧木类型、嵌合体类型三种类型的植株。

培育多倍体植株是增加花朵直径大小的有效方法之一。

良好的栽培条件,能使植物进行充分的营养生长,从而获得可遗传的花朵直径增加的性状。

增加重瓣性,花朵的直径也一定随之增加。

栽培措施并不能从根本上解决花朵大小的问题。

花诱导到花分化启动是花芽形成和发育的关键阶段。

激素主要通过对蛋白质或酶的合成和酶的活性的调节来控制调节植物的变化。

在植物开花过程中,基因完全受日照长度的影响。

大多数光周期植物没有明显的幼年期,但随着年龄的增加,对日长的敏感度增加。

被子植物中较原始的类型其花被是由螺旋状排列的苞片状物和花萼组成的,如木兰属植物。

重瓣花大致有2种起源方式,即积累起源、重复起源。

在人工选择的条件下,从多一两个花瓣的单株开始,经过若干代的选择,可使花瓣数目逐年增加,直至最后形成重瓣花。

一般来讲重瓣花是由一对基因控制的显性性状。

园林植物的育种目标就是育成花卉新品种所具备的目标性状。

园林植物育种的主要目标性状包括延长花期,观赏品质优良的花卉。

抗逆性主要是指植物对不良环境的适应能力,随着花卉生产的发展,抗性育种已经成为花卉育种的一个重要的目标。

延长花期就是使花卉品种能提早开花

种质资源是具有一定的遗传基础,表现一定的优良性状,并能将特定的遗传信息传递给后代的生物资源的总和。

种质创新是指对原有种质资源的扩展或改进。

就地保护是指在自然保护区、森林公园、植物园、公园等人工环境中保存园林植物种质资源。

种质资源保存的方式包括离体保存、就地保存两种方式。

木本植物引种驯化成功的最大可能性是在于树种原产地和新栽培区气候条件有相似的地方。

引种驯化的步骤包括:调查和登记、检疫、试验这三步。

当植物从南向北引种时,可适当的提早播种,这样做能增强植物组织的充实度,提高抗寒能力。

影响植物生长发育的主要温度因子有:年平均气温、临界气温及其持续时间。

芽变是体细胞突变的一种形式,在植物体芽的分生组织细胞中,当变异的芽萌发长成枝条或个体在性状上表现出与原类型不同的现象就成为芽变。

芽变的稳定性和不稳定性的实质有二:一是基因突变的可逆性,另一个是与芽变的嵌合结构有关。

在芽变性状的平衡性理论中,亲缘关系较远的物种之间经常发生性状相似的突变。

芽变的细胞学基础包括:嵌合体与芽变的发生、芽变的转化。

有性杂交育种可以分为近缘杂交育种和远缘杂交育种两种。

杂交的亲本选择是指根据品种的选育目标,选用具有优良性状的品种类型作为杂交的亲本。

亲本选配的原则一般包括:亲本的性状互补、以具有最多的优良性状的亲本作为母本、根据性状的遗传规律选配亲本。

为了提高杂交结实率,应该尽可能的选用杂交结实率高的品种作为父本。

远缘杂交可以分为有性远缘杂交和无性远缘杂交两种方式( )

远缘杂交中后代的分离类型可以分为综合性状类型、亲本性状类型、 新物种类型。

远缘杂交不稔性的克服方法有杂种染色体加倍、回交法、延长选择世代三种方法。

同科同属不同物种之间的杂交为远缘杂交。

杂种优势的大小,取决于双亲的遗传差异和互补的程度。

提高杂种优势的根本途径是提高杂交亲本的纯度。

杂种优势在f1中表现较明显,f2代以后逐渐增强。

杂交亲本遗传差异越小,血缘关系越近,其杂交后代的杂种优势越强。

多倍体在遗传表现上具有的特点有:巨大性、品质与产量的提高、生理特性的改变等。

大约一半的被子植物、1/3以上的禾本科植物是多倍体。

在一般情况下,同源多倍体大多结实率较低,表现出了相当程度的不孕性。

秋水仙素的有效浓度和处理时间是诱导多倍体的关键。

品种或品种群的名称是由它所隶属的属或者更低的分类单位的正确名称和品种或品种群加词共同组成。

登录品种的程序中,育种者需要向登录权威提交拟登录品种的文字、图片、育种亲本、育种过程等有关材料。

植物新品种审查步骤包括初步审查和实质审查两个步骤。

植物新品种保护有利于规范育种行业,激励植物种质创新。

花粉生活力测定的方法较多,常用的有:形态鉴定、花粉萌发鉴定、染色鉴定。

用ttc染色法鉴定花粉活力时,可根据花粉染不染成红色来判断有无生命力,从而测定花粉生活力。

大多数植株正常的花粉呈圆球形,积累着较多的淀粉,用i2-ki溶液染色时呈红色。

花粉生活力的高低直接影响植物授粉、受精乃至结果。

选择的遗传机制就是通过选择改变群体内的基因频率和基因型频率。

选择要在产生变异的群体中进行、供选择育种的群体要够大,选择育种可以在不同的环境条件下进行。

选择育种的方法可以分为混合选择、单株选择、评分比较选择法、相关性状选择法、全息定域选种法、无性系选择法和分子标记辅助选择育种7种方法。

一般选择育种要经过确定育种目标、建立原始材料圃、株系选择圃和品系鉴定圃等。

有性杂交的类别包括单交与回交、多系杂交、多父本混合授粉杂交。

有性杂交在选配亲本时,应注意选择此性器官发育健全,结实性强的种类作为母本。
