词汇对比与辨析

核心差别

diploidy 强调二倍性是指生物体细胞中染色体组数为两套的遗传状态,polyploidy 则侧重多倍性是指生物细胞中染色体组数超过正常二倍体数目的遗传现象

使用场景对比

对比方面diploidypolyploidy
核心含义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。多倍性是指生物细胞中染色体组数超过正常二倍体数目的遗传现象,常见于植物育种和某些疾病研究中。
词性未知名词
使用语域通常作为名词使用,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。通常用作名词,在句子中作主语、宾语或表语,描述遗传状态或现象。

常见误用提醒

使用 diploidy:The diploidy is important for cell function. → 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。)

使用 diploidy:Humans have diploidy cells. → 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'。)

使用 polyploidy:Polyploidy is a verb that means to have many chromosomes. → 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。)
