单倍体是指细胞中仅含有一套染色体的状态,常见于生殖细胞,与二倍体相对。

用法要点

句型搭配

通常用作形容词修饰名词,描述细胞或生物体的染色体状态,也可作名词指代单倍体细胞。

• haploid cell
• haploid organism
• haploid number

介词用法

常与介词'in'连用表示在某种状态或条件下,如'in haploid form';也可与'of'搭配表示所属关系。

• in haploid state
• haploid of the species
• haploid in plants

语域说明

主要用于生物学、遗传学、医学等专业领域,属于学术词汇,日常对话中较少使用。

• haploid genome
• haploid phase
• haploid set

基础例句

In biology class, we learned that sperm and egg cells are haploid.

在生物课上,我们学到精子和卵细胞是单倍体。

The haploid number of chromosomes in humans is 23.

人类的单倍体染色体数目是23条。

Some plants can exist in both haploid and diploid forms.

有些植物可以同时以单倍体和二倍体形式存在。

Understanding haploid cells is important for genetics.

理解单倍体细胞对遗传学很重要。

高级例句

The haploid genome of this yeast strain has been fully sequenced for research purposes.

这种酵母菌株的单倍体基因组已为研究目的完全测序。

In plant breeding, haploid induction techniques are used to accelerate the development of pure lines.

在植物育种中,单倍体诱导技术被用于加速纯系的开发。

The study compared gene expression in haploid versus diploid embryonic stem cells.

这项研究比较了单倍体与二倍体胚胎干细胞中的基因表达。

常见错误

❌ 错误:This cell is haploidy.
✓ 正确:This cell is haploid.

'haploid'是形容词,直接修饰名词,不需要加后缀'-y'。'haploidy'是名词,指单倍性状态,但在此句中应用形容词形式。

❌ 错误:Haploid means having two sets of chromosomes.
✓ 正确:Haploid means having one set of chromosomes.

单倍体的定义是仅含有一套染色体,二倍体(diploid)才是有两套染色体,这是基础概念错误。

近义词辨析

monoploid

'monoploid'也指单倍体,但更强调染色体组的基本数目,常用于植物学;'haploid'更通用,广泛用于生物学各领域。

In some contexts, 'haploid' and 'monoploid' are used interchangeably, but 'haploid' is more common in general genetics.

diploid

'diploid'指二倍体,即细胞中含有两套染色体,与'haploid'(单倍体)相对;两者描述不同的染色体倍数状态。

Most human cells are diploid, while gametes are haploid.
