回帖：heredity (n.)
1530s, "inheritance, succession," from Middle French hérédité, from Old French eredite "inheritance, legacy" (12c.), from Latin hereditatem (nominative hereditas) "heirship, inheritance, an inheritance, condition of being an heir," from heres (genitive heredis) "heir, heiress," from PIE root *ghe- "to be empty, left behind" (source also of Greek khēra "widow"). Legal sense of "inheritable quality or character" first recorded 1784; the modern biological sense "transmission of qualities from parents to offspring" seems to be found first in 1863, introduced by Herbert Spencer.

15世纪30年代，“继承，继承”，来自法国中部hérédité，来自旧的法国埃雷德人“继承，继承”（12c.），来自拉丁继承（提名继承）“继承，继承，继承，作为继承人的条件，”来自heres（亲生继承）“继承人，继承人”，来自PIE-root*ghe-“为空，留守”（希腊语khēra“寡妇”的来源）。法律意义上的“可继承的品质或特征”最早记载于1784年；现代生物学意义上的“品质从父母传给后代”似乎最早发现于1863年，由赫伯特·斯宾塞提出。
