A geneticist is a person — a scientist — whose work is genetics: how living things pass qualities to their children through genes. The -ist ending tells you it is the person, not the subject.

A geneticist geneticist is是 a person一個人 — a scientist——是科學家 — whose work is他的工作是 genetics研究genetics: how living things pass qualities to their children through genes也就是生物怎麼透過基因把特質傳給下一代。 The -ist ending字尾-ist tells you表示 it is the person, not the subject.指的是「人」，不是那個學科本身。

A geneticist may look at plants, animals, or people; some work in hospitals, some in labs, some on farms. They may study why an illness runs in a family, how to grow stronger crops, or how two living things are related.

A geneticist may look at geneticist可能研究 plants, animals, or people;植物、動物或人; some work in有些人在 hospitals,醫院, some in labs,有些在實驗室, some on farms.有些在農場工作。 They may study他們可能研究 why an illness runs in a family,為什麼某種病會在一個家族裡一直出現, how to grow stronger crops,怎麼種出更強壯的作物, or how two living things are related.或是兩個生物之間有什麼親緣關係。

Though actually, a short line you sometimes see (“the study of how qualities are passed on in genes”) is the meaning of genetics, not geneticist. If you want the study, say genetics; if you want the expert, say geneticist.

Though actually,不過其實， a short line you sometimes see你有時候會看到的一句話 ("the study of how qualities are passed on in genes")「研究特質怎麼透過基因傳下去」 is the meaning of genetics, not geneticist.其實是genetics的意思，不是geneticist。 If you want the study,如果你要講那門學問, say genetics;就說genetics; if you want the expert,如果你要講那個專家, say geneticist.就說geneticist。

It is a job-word, like artist or scientist, not the name of the field itself.

It is a job-word,它是一個職業詞, like artist or scientist,跟artist、scientist一樣, not the name of the field itself.不是那個學科本身的名稱。
