    有4条染色体,B项错误;图2表示有丝分裂过程中的某阶段,则该阶段包括有丝分裂前期和中期,这两个时期细胞中不会发生染色体着丝粒分裂,C项正确;图2中a:b:c=1:2:2,a表示染色体,可能处于有丝分裂前期、中期,此时染色体数目与体细胞中的相同,D项正确。15.答案BD命题透析本题以马的毛色遗传为情境,考查分离定律的应用,旨在考查考生的理解能力、获取信息的能力和实验与探究能力,以及生命观念、科学思维和科学探究的核心素养。思路点拨由于正常情况下,一匹母马一次只能生一匹小马,为了在一个配种季节里完成这项鉴定,应该让该栗色公马与多匹白色母马杂交,观察统计子代小马的毛色,A、C两项错误。若后代全是栗色马,则M可能是纯合子;若后代白色马:栗色马=1:1,则M是杂合子,B、D两项正确。16.答案BC命题透析本题以水稻的非糯性和糯性为情境,考查分离定律实验及应用的相关知识,旨在考查考生的理解能力、获取信息的能力和实验与探究能力,以及生命观念、科学思维的核心素养。思路点拨花粉出现这种比例的原因是F1形成配子时,成对的遗传因子彼此分离,分别进人两个不同的配子中,A项正确;本实验中只涉及一对等位基因,无法验证基因的自由组合定律,B项错误;F,为杂合子,根据F花粉加碘液的颜色变化不能确定性状的显隐性,C项错误;若相关基因用A、a表示,F,的基因型为Aa,自交产生F2的基因型为AA、Aa、aa,有非糯性和糯性两种表型,产生的花粉中有A和a两种配子,加碘液染色,在显微镜下观察到的颜色有蓝黑色和橙红色两种,D项正确。17.答案AC命题透析本题以白化病的遗传为情境,考查分离定律的应用,旨在考查考生的理解能力和获取信息的能力,以及生命观念、科学思维的核心素养。思路点拨组合二的夫妇正常,后代出现了白化病,可知白化为隐性性状,夫妇的基因型均为Aa,生育正常孩子的概率为75%,A项正确,D项错误;组合一的夫妇和子代都正常,该对夫妇中的一个很可能为纯合子,另个人可能是纯合子也可能是杂合子,B项错误;组合三的婚配方式中正常个体(Aa)与隐性个体(aa)婚配,类似于测交,C项正确。18.答案ABC命题透析本题以蝴蝶的翅色和眼色遗传柱形图为情境,考查自由组合定律的应用,旨在考查考生的理解能力和获取信息的能力,以及生命观念、科学思维的核心素养。思路点拨据图分析可知,F1中紫翅:黄翅=3:1,绿眼:白眼=1:1,因此,实验中所用亲本紫翅绿眼蝴蝶的基因型是AaBb,紫翅白眼蝴蝶的基因型是Aabb,A项正确;亲本的基因型为AaBb、Aabb,F,中紫翅绿眼的基因型是AABb、AaBb,AABb占的比例为(1/4)×(1/2)=1/8,AaBb占的比例为(2/4)×(1/2)=2/8,因此紫翅绿眼所占的比例是1/8+2/8=3/8,B项正确;亲本杂交组合为AaBb×Aabb,后代表型及比例为紫翅绿眼:紫翅白眼:黄翅绿眼:黄翅白眼=3:3:1:1,黄翅绿眼蝴蝶的基因型是aaBb,所占比例为(1/4)×(1/2)=1/8,C项正确;如果让F,中两只黄翅绿眼蝴蝶(aaBb)交配,得到的F2中表型有2种,黄翅绿眼和黄翅白眼,比例为3:1,D项错误。19.答案(除注明外,每空1分,共13分)(1)下一次分裂完成纺锤丝染色体(后两空答案可互换)(2)专门化产生完整有机体分化成其他各种细胞植物组织培养(2分)(3)自由基DNA一蛋白质细胞坏死由基因所决定的细胞自动结束生命(2分)命题透析本题考查细胞的生命历程,旨在考查考生的理解能力,以及生命观念、科学思维的核心素养。一4
