Amphigony
Definition
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.
