• Pinyin (with tone marks): yí chuán
• Part of Speech: Noun, Verb
• HSK Level: HSK 6
• Concise Definition: The passing on of physical or mental characteristics genetically from one generation to another.
• In a Nutshell: 遗传 (yíchuán) is the direct equivalent of the scientific term “heredity” or the verb “to inherit” in a biological sense. It's used to talk about the traits you get from your parents and ancestors through your genes—like your eye color, height, and sometimes even talents or predispositions to certain health conditions. It's a precise term used in both scientific and everyday contexts.

• 遗 (yí): This character means “to leave behind” or “to hand down.” Think of a legacy or something left over from a previous generation. For example, 遗产 (yíchǎn) means “inheritance” in the sense of property or assets.
• 传 (chuán): This character means “to pass on,” “to transmit,” or “to spread.” It's used in words like 传统 (chuántǒng), meaning “tradition,” which is passed down through generations.
• Combined Meaning: The two characters logically combine to mean “to hand down and pass on.” In the context of 遗传 (yíchuán), this specifically refers to the biological traits passed down from parents to their children.

While the scientific concept of heredity is universal, discussions around 遗传 (yíchuán) in China often tap into deep-seated cultural values surrounding family and lineage (血统, xuètǒng). Family is the cornerstone of Chinese society, and ancestry is highly valued. It is very common and natural to comment on which parent or grandparent a child resembles. Pointing out that a child has 遗传了 (yíchuán le - inherited) their mother's eyes or their father's nose is a common way to build rapport and acknowledge family bonds. This differs slightly from Western cultures, where such comments might be seen as more of a passing observation rather than a confirmation of family continuity. Furthermore, the concept is sometimes extended colloquially to talents and personality traits. Saying someone's musical ability is from 遗传 is a way of acknowledging a family's gifted lineage. This reflects a cultural perspective where individual traits are often viewed as part of a larger family identity.

遗传 is a versatile word used in both formal, scientific settings and casual, everyday conversations. Its connotation is generally neutral and factual.

• Scientific and Medical Context: In a doctor's office or a biology class, 遗传 is used precisely. You'll hear it in terms like 遗传病 (yíchuánbìng, genetic disease), 遗传学 (yíchuánxué, genetics), and 遗传基因 (yíchuán jīyīn, hereditary gene).
• Everyday Conversation: This is where the term is used most frequently by learners. People use it to talk about:

The biggest pitfall for English speakers is confusing 遗传 (yíchuán) with 继承 (jìchéng). They can both be translated as “to inherit,” but their usage is completely different.

• 遗传 (yíchuán): For BIOLOGICAL traits only. (Genes, appearance, medical conditions).
• 继承 (jìchéng): For MATERIAL or ABSTRACT possessions. (Money, property, a throne, a title, a company).

Common Mistake Example:

• Incorrect: 我遗传了我祖父的房子和钱。 (Wǒ yíchuán le wǒ zǔfù de fángzi hé qián.)
• Why it's wrong: This sentence incorrectly uses 遗传 for property and money. You cannot biologically inherit a house.
• Correct: 我继承了我祖父的房子和钱。 (Wǒ jìchéng le wǒ zǔfù de fángzi hé qián.) - I inherited my grandfather's house and money.

Another potential point of confusion is 遗传 (yíchuán) vs. 传染 (chuánrǎn).

• 遗传 (yíchuán): Hereditary (from parent to child).
• 传染 (chuánrǎn): Contagious/Infectious (from one person to another, like a cold or flu).

• 基因 (jīyīn) - Gene. The fundamental unit of heredity that is transferred from a parent to offspring.
• 遗传学 (yíchuánxué) - Genetics. The scientific study of heredity.
• 遗传病 (yíchuánbìng) - Genetic disease / Hereditary disease. A disease caused by abnormalities in an individual's genetic material.
• 继承 (jìchéng) - To inherit (assets, title, property). The most important term to distinguish from 遗传.
• 传染 (chuánrǎn) - To infect, contagious. Refers to the transmission of disease from person to person, not parent to child.
• 血统 (xuètǒng) - Bloodline, lineage, ancestry. A more traditional and cultural concept related to family descent.
• 天生 (tiānshēng) - Innate, inborn. Describes a quality one is born with, which is often a result of 遗传.
• 后代 (hòudài) - Descendants, posterity. The generation that receives the genetic information.
