word-forming element meaning "birth, origin, creation," from Greek genesis "origin, creation, generation," from gignesthai "to be born," related to genos "race, birth, descent" (from PIE root *gene- "give birth, beget," with derivatives referring to procreation and familial and tribal groups).
"reproduction without fertilization or sexual union," 1849, from Greek parthenos "a virgin," a word of unknown origin, + -genesis "birth, origin, creation." Related: Parthenogenetic.
