polyploid 指生物体或细胞具有多套染色体组的遗传状态,常见于植物育种和某些动物中,用于描述多倍体生物或其特征。

用法要点

句型搭配

作为名词时,常用于描述生物类型或遗传特征,如 'a polyploid' 或 'polyploids';作为形容词时,修饰名词如 'polyploid plant' 或 'polyploid cells',强调多倍体属性。

• a polyploid organism
• polyploid species
• polyploid condition

介词用法

常与 'in' 连用表示在某种生物或细胞中,如 'polyploid in plants';与 'of' 连用表示多倍体的来源或类型,如 'polyploid of wheat';在学术语境中,'with' 用于描述伴随特征,如 'cells with polyploid nuclei'。

• polyploid in animals
• polyploid of the genus
• with polyploid traits

语域说明

主要用于生物学、遗传学、农业等学术和专业领域,日常对话中较少使用;在正式写作和科学报告中常见,口语中可能简化或使用更通俗术语。

• scientific paper on polyploidy
• agricultural report
• genetics textbook

基础例句

In biology class, we learned that some plants are polyploid, which helps them adapt to different environments.

在生物课上,我们学到有些植物是多倍体,这有助于它们适应不同环境。

Farmers sometimes use polyploid crops because they can have larger fruits or better resistance.

农民有时会种植多倍体作物,因为它们可能果实更大或抗性更强。

If a cell becomes polyploid, it might have extra copies of genes, which can affect its function.

如果一个细胞变成多倍体,它可能拥有额外的基因副本,这会影响其功能。

高级例句

Recent studies in genetics have shown that polyploid organisms often exhibit increased genetic diversity and adaptability in evolutionary processes.

遗传学近期研究表明,多倍体生物在进化过程中常表现出更高的遗传多样性和适应性。

In agricultural biotechnology, inducing polyploidy in crops is a common technique to enhance yield and stress tolerance, as seen in polyploid wheat varieties.

在农业生物技术中,诱导作物多倍体是提高产量和抗逆性的常用技术,例如在多倍体小麦品种中。

The research paper analyzed polyploid cells in cancer biology, suggesting that polyploidization may contribute to tumor progression and drug resistance.

这篇研究论文分析了癌症生物学中的多倍体细胞,指出多倍体化可能促进肿瘤进展和药物抗性。

常见错误

❌ 错误:This plant is a polyploidy.
✓ 正确:This plant is polyploid.

错误:误将名词 'polyploidy'(多倍性)用作形容词。正确:'polyploid' 本身可作为形容词,直接修饰名词,表示'多倍体的'。应使用形容词形式来描述生物特征。

❌ 错误:Polyploid means many times of chromosomes.
✓ 正确:Polyploid refers to an organism or cell with multiple sets of chromosomes.

错误:释义不准确且语法不当。正确:'polyploid' 特指具有多套染色体组的生物体或细胞,而不仅仅是染色体数量多。应使用标准定义,避免模糊描述。

近义词辨析

polyploidy

'polyploidy' 是名词,指多倍性这种遗传状态或现象;而 'polyploid' 可作为名词(多倍体生物)或形容词(多倍体的),更具体描述实体或属性。

Polyploidy is common in plants (现象), while a polyploid plant may have larger leaves (实体).

aneuploid

'aneuploid' 指非整倍体,染色体数量异常但不是完整倍数;而 'polyploid' 指整倍体,染色体组为完整倍数增加,常用于描述正常变异或育种。

Aneuploid cells often cause diseases like Down syndrome, whereas polyploid cells are normal in some plants like wheat.
