下列关于植物体细胞杂交或植物细胞质遗传的叙述中，错误的是（）
A．利用植物体细胞杂交技术可克服生殖隔离的限制，培育远缘杂种
B．不同种植物原生质体融合的过程属于植物体细胞杂交过程
C．两个不同品种的紫茉莉杂交，正交、反交所得F1的表现型一致
D．两个不同品种的紫茉莉杂交，F1的遗传物质来自母本的多于来自父本的
参考答案：C
解析：利用植物体细胞杂交技术可克服生殖隔离的限制，培育远缘物种的杂种，所以A正确；不同种植物细胞的原生质体融合的过程是植物体细胞杂交过程，所以B正确；不同品种的紫茉莉是同一物种，其杂交的正、反交结果是一样的，所以C错误；两个不同品种的紫茉莉杂交，F1的遗传物质有来自母本细胞核DNA，还有细胞质中的DNA，以及来自父本的细胞核DNA，所以D正确。

| He was put in a small ward(病房) with another patient in a hospital. The ward had nothing 1 a small window that 2 to the outside world.

The doctor thought that he did not want to face a(n) 19 bed every day, so he promised to 20 another ward for him. Just the moment he was lifted onto the stretcher(担架), he spotted the scene outside the window-a pale wall. | ||||
