Sexual reproduction; the formation of offspring through the union of male and female reproductive cells.
From Greek 'gamos' (sexual union) + '-geny' (origin/generation). Alternative or synonym for 'gamogenesis' with slightly older usage.
Gamogeny explains why siblings look both similar and different—each carries a random reshuffling of Mom and Dad's genetic cards, creating infinite variation.
