Amphimixis
Definition
A fundamental biological process of true sexual reproduction, consisting of the structural fusion of two gametes of opposite sexes (the male and female pronuclei), leading to the formation of a diploid zygote (fertilized egg). This mechanism forms the basis of Mendelian genetic recombination, ensuring the transmission of parental hereditary traits and genomic diversity within the species.
