常见错误

❌ 错误:Polyploidy is a verb that means to have many chromosomes.
✓ 正确:Polyploidy is a noun that refers to the condition of having multiple sets of chromosomes.

错误地将多倍性用作动词,它实际上是名词,描述染色体数目异常的状态,应纠正为名词用法。

❌ 错误:This animal shows polyploidy in its behavior.
✓ 正确:This plant shows polyploidy in its cells.

多倍性主要指细胞遗传特征,常见于植物,动物中较少,且与行为无关,应改为描述植物或细胞层面的例子。

近义词辨析

aneuploidy

多倍性指染色体组数成倍增加(如三倍体、四倍体),而非整倍性指染色体数目不成倍增减(如单体、三体),后者常与疾病相关。

Polyploidy involves whole genome duplication, whereas aneuploidy involves gains or losses of individual chromosomes.

ploidy

多倍性是倍性的一种特定类型,指超过二倍体的状态;倍性是一个更广泛的术语,包括单倍体、二倍体、多倍体等所有染色体组数状态。

Polyploidy is a subset of ploidy, specifically referring to conditions with more than two sets of chromosomes.
