表现型是指生物体在特定环境下表现出的可观察特征,由基因型和环境共同决定,常用于生物学和遗传学领域。

用法要点

句型搭配

phenotype 通常作为名词使用,常见于描述生物特征或遗传研究,常与动词如 exhibit、determine 或形容词如 dominant、recessive 搭配。

• exhibit a phenotype
• determine the phenotype
• dominant phenotype

介词用法

phenotype 常与介词 of 连用,表示属于某个生物或群体的表现型,也可用 in 表示在特定环境中的表现。

• phenotype of the plant
• phenotype in humans
• phenotype under stress

语域说明

phenotype 是学术和科学术语,主要用于生物学、遗传学、医学等专业领域,日常对话中较少使用,但在科普或教育场景可能出现。

• scientific phenotype analysis
• medical phenotype study
• educational phenotype discussion

基础例句

The plant exhibits a green phenotype due to its genetic makeup.

这种植物因其基因组成而表现出绿色的表现型。

In biology class, we learned how environment can influence phenotype.

在生物课上,我们学习了环境如何影响表现型。

The doctor explained that the patient's phenotype might change with treatment.

医生解释说,患者的表型可能会随着治疗而改变。

高级例句

The research focuses on the correlation between genotype and phenotype in cancer cells.

这项研究专注于癌细胞中基因型与表型之间的相关性。

Agricultural scientists are breeding crops to enhance desirable phenotypes for higher yield.

农业科学家正在培育作物,以增强理想表型来提高产量。

常见错误

❌ 错误:The phenotype is same as genotype.
✓ 正确:The phenotype is different from the genotype.

错误在于混淆了表型和基因型。表型是可观察特征,而基因型是遗传信息;正确用法应强调它们的区别,例如使用 different from 来对比。

❌ 错误:He has a strong phenotype.
✓ 正确:He exhibits a dominant phenotype.

错误在于使用不准确的形容词 strong。在遗传学中,表型常用 dominant 或 recessive 描述;正确用法应使用专业术语如 dominant phenotype 来表示显性特征。

近义词辨析

trait

trait 更泛指生物的任何特征或特性,可以是遗传或环境导致,而 phenotype 特指由基因型和环境共同决定的可观察表现,更具科学精确性。

Eye color is a trait, but as a phenotype, it results from specific genetic interactions.

characteristic

characteristic 是通用词,描述任何显著特点,可用于生物或非生物;phenotype 则专用于生物学,强调遗传和环境因素在生物表现中的综合作用。

A characteristic of the species is its size, but the phenotype includes how size varies with nutrition.
