#automixis

• Automixis — A modified form of sexual reproduction or self-fertilization characterized by the fusion of two haploid nuclei originating from the same mother cell or the same individual, without the intervention of any external gamete. In genetics and mycology, this biological process ensures the perpetuation of the species under extreme ecological isolation, allowing the restoration of the zygote's diploid state from a single lineage, though it reduces the genetic variability of offspring.
• Automictic parthenogenesis — A form of parthenogenesis (virgin reproduction) in which an egg cell develops without being fertilized by a sperm cell, but diploidy (the full chromosome count) is spontaneously restored through an internal meiotic or mitotic mechanism, such as the fusion of the egg with its own polar body or nuclear chromosome duplication. This endogenous structural process ensures the complete transmission of maternal genetic material, generating offspring that are genetically partial or total clones of the mother.
