heterozygote 指在遗传学中,一个个体在特定基因座上拥有两个不同等位基因的状态,即杂合体或异型合子。

用法要点

句型搭配

heterozygote 通常作为名词使用,常见于描述遗传特征的句子中,如 'is a heterozygote' 或 'carries a heterozygote',用于说明个体的基因型。

• The individual is a heterozygote for the gene.
• She carries a heterozygote allele.

介词用法

heterozygote 常与介词 'for' 连用,表示针对特定基因或性状的杂合状态,例如 'heterozygote for a mutation',强调基因的具体类型。

• heterozygote for the cystic fibrosis gene
• heterozygote for a recessive trait

语域说明

heterozygote 是专业术语,主要用于生物学、医学和遗传学等学术领域,在非正式日常对话中较少使用,通常用更通俗的 'carrier' 或 'mixed genes' 代替。

• In genetics class, we learned about heterozygotes.
• He's a heterozygote in the study.

基础例句

In biology class, we learned that a heterozygote has two different alleles for a trait.

在生物课上,我们学到杂合体在一个性状上有两个不同的等位基因。

My friend is a heterozygote for blue eyes, so her children might inherit it.

我的朋友是蓝眼睛的杂合体,所以她的孩子可能会遗传到这个特征。

The doctor explained that being a heterozygote doesn't always show symptoms.

医生解释说,作为杂合体并不总是表现出症状。

高级例句

The study found that heterozygote advantage can increase genetic diversity in populations.

研究发现,杂合体优势可以增加种群中的遗传多样性。

In genetic counseling, identifying heterozygotes is crucial for assessing disease risk.

在遗传咨询中,识别杂合体对于评估疾病风险至关重要。

The research paper discusses heterozygote frequencies in evolutionary biology models.

这篇研究论文讨论了进化生物学模型中的杂合体频率。

常见错误

❌ 错误:He is heterozygote for the disease.
✓ 正确:He is a heterozygote for the disease.

错误在于缺少冠词 'a',heterozygote 是可数名词,通常需要冠词或限定词,如 'a heterozygote' 或 'the heterozygote',以符合英语语法规则。

❌ 错误:This heterozygote means mixed genes.
✓ 正确:A heterozygote has mixed alleles for a gene.

错误在于用词不准确,'mixed genes' 过于口语化且可能误导,正确说法应强调等位基因的差异,使用 'mixed alleles' 或直接描述杂合状态,以保持术语的专业性。

近义词辨析

carrier

carrier 通常指携带隐性基因但不表现症状的个体,更侧重于疾病传播的语境,而 heterozygote 是更广泛的遗传学术语,指任何拥有两个不同等位基因的状态,不一定与疾病相关。

A carrier of a recessive disorder is often a heterozygote, but not all heterozygotes are carriers for diseases.

hybrid

hybrid 常用于描述不同物种或品种的杂交后代,强调混合来源,而 heterozygote 特指单个基因座上的等位基因差异,是更精确的遗传学概念,不涉及物种层面。

A hybrid plant may result from crossbreeding, but its genetic makeup can include both heterozygotes and homozygotes.
