种系指生物体中能够遗传给后代的生殖细胞系,与体细胞相对,在遗传学和生物学中常用于描述遗传物质的传递。

用法要点

学术语境使用

germline 主要用于生物学、遗传学、医学等学术领域,描述与遗传相关的概念,日常对话中较少使用。

• germline mutation
• germline cells
• germline transmission

名词搭配结构

常作为名词修饰语,与 mutation、cells、therapy 等词搭配,形成复合名词,表示与遗传相关特定方面。

• germline editing
• germline inheritance
• germline engineering

介词用法

在句子中常与 in、of、for 等介词连用,表示在种系中、种系的或用于种系的目的。

• mutations in the germline
• modification of the germline
• therapies for germline disorders

基础例句

Scientists are studying how germline mutations can affect future generations.

科学家正在研究种系突变如何影响后代。

In biology class, we learned that germline cells are different from somatic cells.

在生物课上,我们学到种系细胞与体细胞不同。

The doctor explained that some diseases are passed down through the germline.

医生解释说有些疾病是通过种系遗传的。

高级例句

Recent advances in CRISPR technology have raised ethical questions about germline editing in humans.

CRISPR 技术的最新进展引发了关于人类种系编辑的伦理问题。

The research focuses on identifying germline variants associated with increased cancer risk.

这项研究专注于识别与癌症风险增加相关的种系变异。

Germline therapy aims to correct genetic defects at the embryonic stage to prevent hereditary diseases.

常见错误

❌ 错误:The germline of the plant is growing well.
✓ 正确:The germline cells of the plant are being studied for genetic traits.

germline 不是指植物的生长状态,而是遗传学概念,应改为描述种系细胞或相关研究。

❌ 错误:He has a strong germline.
✓ 正确:He carries a germline mutation that may affect his children.

germline 不能用来形容个人体质强弱,应具体说明种系突变或遗传特征。

近义词辨析

hereditary

hereditary 强调特征或疾病从父母遗传给后代,是形容词;germline 是名词,特指遗传物质的生殖细胞系。

Hereditary diseases (遗传性疾病) may involve germline mutations (可能涉及种系突变)。

genetic

genetic 泛指与基因相关的一切,范围更广;germline 专指可遗传的生殖系部分,是 genetic 的一个子集。

Genetic testing (基因检测) can include both somatic and germline analysis (可以包括体细胞和种系分析)。
