二倍性是指生物体细胞中染色体组数为两套的遗传状态,常见于大多数动物和植物的体细胞。

用法要点

句型搭配

通常作为名词使用,描述遗传特征,常与动词如maintain、lose或形容词如normal、stable搭配,用于说明染色体状态。

• maintain diploidy
• lose diploidy
• normal diploidy

介词用法

常用介词in表示在某种生物或细胞中,如in humans或in somatic cells;也可用of表示所属关系,如diploidy of the species。

• diploidy in plants
• diploidy of the organism
• diploidy in somatic cells

语域说明

主要用于生物学、遗传学等学术领域,日常对话中较少使用,属于专业术语,适合在科学讨论或教育场景中应用。

• academic papers on diploidy
• genetics textbooks mention diploidy
• research in diploidy

基础例句

In biology class, we learned that most animals have diploidy in their body cells.

在生物课上,我们学到大多数动物的体细胞具有二倍性。

Plants often maintain diploidy to ensure genetic stability during growth.

植物通常保持二倍性,以确保生长过程中的遗传稳定性。

The teacher explained that diploidy is common in humans, with two sets of chromosomes.

老师解释说,二倍性在人类中很常见,有两套染色体。

When cells divide, they usually retain diploidy to pass on traits correctly.

细胞分裂时,它们通常保留二倍性,以正确传递性状。

高级例句

Research indicates that diploidy in somatic cells is crucial for organismal development and function.

研究表明,体细胞中的二倍性对生物体的发育和功能至关重要。

In genetic engineering, maintaining diploidy can prevent unwanted mutations in modified organisms.

在基因工程中,保持二倍性可以防止改造生物体中出现不必要的突变。

The study compared diploidy across different species to understand evolutionary adaptations.

这项研究比较了不同物种的二倍性,以理解进化适应。

Biotech companies monitor diploidy in cell cultures to ensure product consistency and safety.

常见错误

❌ 错误:The diploidy is important for cell function.
✓ 正确:Diploidy is important for cell function.

错误在于使用了定冠词'the',而'diploidy'作为抽象名词通常不加冠词,除非特指某种二倍性状态。

❌ 错误:Humans have diploidy cells.
✓ 正确:Humans have diploid cells.

错误在于混淆了名词'diploidy'和形容词'diploid'。'diploidy'指状态,应用形容词'diploid'修饰名词'cells'。

近义词辨析

diploid

'diploid'是形容词,描述具有两套染色体的细胞或生物;而'diploidy'是名词,指这种遗传状态本身。

Diploid cells exhibit diploidy, meaning they contain two sets of chromosomes.

polyploidy

'polyploidy'指染色体组数超过两套的状态,如三倍性或四倍性;而'diploidy'特指两套染色体,是更常见的遗传形式。

While diploidy is typical in animals, polyploidy is more common in plants, such as in wheat.
