核心畫面
You can picture a single line of instructions tucked inside every cell — too small to see, but carrying an order like "make this person's eyes brown" or "grow this leaf long and thin." The line was copied from the parents and handed on unchanged, so the same instruction sits in a child's cells that sat in the mother's. That is why gene is used for anything a family seems to pass along without choosing to: the word points at the instruction, not at the trait you can see.

可以想成每個細胞裡都藏著一行小小的指令——小到看不見，但寫著像「讓這個人的眼睛是棕色」「讓這片葉子長得又細又長」這樣的命令。這行指令是從父母那裡原封不動抄過來、再交下去的，所以孩子細胞裡的那一行，跟母親細胞裡的那一行一模一樣。英文之所以會說 It's in his genes（這是他天生的），就是因為這個字指的是那行指令本身，不是你眼睛看得到的樣子。原始詞典資料6 筆記錄
