- Amphigenesis — A biological process of generating or arising a new organism through true sexual reproduction, requiring the equal participation and structural fusion of male and female reproductive elements (gametes). This phenomenon represents the evolutionary foundation of most higher organisms, being the opposite of asexual reproduction or clonal parthenogenesis.
- Amphigony — A normal form of biparental sexual reproduction requiring the structural and functional fusion of two gametes of opposite sexes, male and female, leading to the formation of a diploid zygote. This fundamental biological process represents the evolutionary basis of genetic variability within higher organisms, being the opposite of parthenogenesis or clonal asexual reproduction.
