34.(11分)刺毛鼠的背上有硬棘毛(简称有刺),体色有浅灰色和深色,浅灰色对深色显性。在实验中封闭饲养的刺毛鼠群体中,偶然发现了一只无刺雄鼠,并终身保留无刺状态。请回答下列问题:

(1)产生该无刺雄鼠的原因是     。有刺基因和无刺基因最本质的区别

        不同。

(2)让这只无刺雄鼠与有刺雌鼠交配, F1全有刺;F1雌雄鼠自由交配,生25只有刺鼠和8只无刺鼠,其中无刺鼠全为雄性。这说明这对相对性状中   是隐性,控制有刺无刺的基因位于   染色体上。

(3)若控制体色的基因为A、a,有刺无刺的基因为B、b,则浅灰色无刺雄鼠的基因型是    。 如果它与深色有刺雌鼠交配子代的表现型为浅灰无刺:浅灰有刺:深色无刺:深色有刺为1:1:1:1,则深色有刺雌鼠基因型为    

(4)刺毛鼠的染色体组成2n=16。如果此无刺雄鼠与有刺雌鼠交配,生了一个染色体组成是14+XXY的无刺个体,若其原因应是亲代中的雄鼠在减数第  分裂过程中发生了差错;此次减数分裂同时产生的另外三个精子的染色体组成应依次为        。是否可能为亲代的雌鼠在减数分裂过程中发生了差错并说明理由

33.(12分)下图甲曲线表示某植物在恒温30℃时光合速率与光照强度的关系,图乙是某同学“探究影响植物光合速率的因素”的实验装置图(瓶中盛有适宜浓度的NaHCO3溶液)。试回答:

(1)图甲曲线中,当光照强度为W点时,叶肉细胞中产生ATP的场所有       

(2)已知该植物光合作用和呼吸作用的最适温度分别为25℃和30℃,在其他条件不变的情况下,将温度调节到25℃,图甲曲线中X点将向      移动,Y点将向      移动。

(3)①据研究发现,当土壤干旱时,植物根细胞会迅速合成某种化学物质X。有人推测根部合成的X运输到叶片,能调节气孔的开闭。他们做了如下实验:从该植株上剪取大小和生理状态一致的3片叶,分别将叶柄下部浸在不同浓度X的培养液中,以分析叶片中X物质浓度与气孔开放程度之间的关系。一段时间后,可以测得有关数据。

 以上方案有两处不完善的地方,请指出来并加以改正。

                                      

                                       

                                      

②方案完善后,测得有关数据,得到下表的结果。(注:气孔导度越大,气孔开启程度越大。)

      










































 分组 
 










































测量指标











































培养液中X的浓度mol/m3

2.47
2.97











































9.28











































叶片中的气孔导度(m2/a)
0.54











































0.43
