Definition
亲缘 refers specifically to blood relationship or kinship ties — the genetic connection between relatives. In biology it describes how closely species or organisms are related through evolution (亲缘关系). Unlike the English 'affinity', which can also mean a natural liking or attraction, 亲缘 is reserved for measured, objective relatedness through descent. You'll encounter it in contexts like 亲缘鉴定 (kinship testing) or 亲缘物种 (related species).
