One of the most productive PIE roots: Latin genus, gēns, generāre; Greek génos, gígnomai; Sanskrit jánas, jan-; English kin, kind, king. The vocabulary of birth, kind, and generation across IE descends from this single root.

Discussion
The root *ǵenh₁- generates what may be the single largest cognate family in Indo-European, spanning the vocabulary of birth, generation, kinship, race, and natural kind. Its reflexes are so numerous in modern European languages that listing them comprehensively is impractical; what follows is representative rather than exhaustive.
Latin genus ("birth, race, kind") and gēns ("clan, people") provide the core: gender, generic, generous (generōsus, "of noble birth"), generation, genesis, genuine (genuīnus, "native, authentic"), genial, genius (originally the divine spirit of generation), gentle (gentīlis, "of the same clan"), gentile, gentry, gene, genetic, genocide, and degenerate. The verbal form generāre ("to beget") gives generate. The compound prōgeniēs ("offspring") gives progeny. The prefix in- + genus gives indigenous ("born in"), ingenious ("inborn talent"), and engine (ingenium, "inborn capacity," then "clever device").
The form nāscī (from *ǵn̥h₁-sk̑-, "to be born") yields nature (nātūra, "birth, character"), native, nation (nātiō, "a people, a birth-group"), natal, neonatal, naive (through French naïf, from nātīvus), innate, and renaissance (renāscentia, "rebirth"). The doublet nature/nation — both from "birth" — encapsulates the conceptual unity of this root.
Greek gígnomai (γίγνομαι, "I am born, I become") and génos (γένος, "race, kind") yield genesis, genealogy, eugenics, pathogenesis, photogenic, autogenous, and the suffix -gen (hydrogen, "water-born"; oxygen, "acid-born").
Sanskrit jánas ("race, people"), jā́ti ("birth, caste"), and janáyati ("begets") continue the root in Indo-Iranian. The concept of jāti ("birth-group") is fundamental to the Indian social system.
In Germanic, *ǵenh₁- yields a family of words through different ablaut grades: kin (from *ǵenh₁-), kind (both the adjective "gentle" and the noun "type," from the sense "natural, of the same birth"), and king (Old English cyning, from *kuningaz, "son of the kin"). The convergence of kind ("type") and kind ("gentle") in English reflects the semantic path: of the same kind > naturally disposed > benevolent.
The sheer scale of the *ǵenh₁- cognate family — nature, nation, gender, gene, kin, kind, king, genesis, genius, gentle, generate, genuine, indigenous, naive, renaissance — makes it arguably the most important single root for understanding the PIE contribution to modern vocabulary.
