等位基因是位于同源染色体相同位置上控制相对性状的基因,是遗传学中的基本概念。

用法要点

句型搭配

常用于描述基因的遗传特性,如“allele for...”表示控制特定性状的等位基因,或“dominant/recessive allele”表示显性或隐性等位基因。

• allele for eye color
• dominant allele
• recessive allele

介词用法

常与介词“for”连用表示基因控制的性状,如“allele for blue eyes”;在学术语境中也可用“of”表示所属关系,如“alleles of a gene”。

• allele for height
• alleles of the gene
• allele in the population

语域说明

主要用于生物学、遗传学等学术领域,日常对话中较少使用,但在科普或医学讨论中可能出现。

• genetic allele
• mutant allele
• wild-type allele

基础例句

My brother and I both inherited the allele for blue eyes from our mother.

我和弟弟都从母亲那里遗传了蓝眼睛的等位基因。

In our biology class, we learned how a recessive allele can skip generations.

在生物课上,我们学到了隐性等位基因如何隔代遗传。

The doctor explained that the disease is caused by a mutant allele.

医生解释说这种疾病是由一个突变等位基因引起的。

高级例句

The research team identified a novel allele associated with increased disease resistance in the population.

研究团队在人群中鉴定出一个与增强疾病抗性相关的新等位基因。

Allele frequency analysis revealed significant genetic variation across different geographical regions.

等位基因频率分析揭示了不同地理区域间显著的遗传变异。

In genetic counseling, understanding the inheritance patterns of specific alleles is crucial for risk assessment.

在遗传咨询中,理解特定等位基因的遗传模式对于风险评估至关重要。

常见错误

❌ 错误:This allele is dominate.
✓ 正确:This allele is dominant.

错误使用了形容词“dominate”(动词,意为“支配”),正确应为“dominant”(形容词,意为“显性的”),描述等位基因的显性特性。

❌ 错误:He has the allele of tall.
✓ 正确:He has the allele for tall height.

错误使用了“of”来表示性状,在英语中通常用“for”连接等位基因和其控制的性状,如“allele for tall height”。

近义词辨析

gene

“gene”指基因的整体概念,而“allele”特指基因在特定位置上的不同形式或变体,强调遗传多样性。

The gene controls eye color, but different alleles determine whether eyes are blue or brown.

variant

“variant”泛指任何遗传变异,包括基因突变或等位基因;而“allele”更具体,指同源染色体上相同位置的基因形式。

A genetic variant may refer to any change, but an allele specifically denotes one form of a gene at a locus.
