Apomixis describes seed production that occurs without fertilization in biological contexts. This process bypasses the fusion of gametes typical of sexual reproduction. For clarity, consider these definitions:
Parthenogenesis: Embryonic development from an unfertilized egg, typically not resulting in seeds.
Apomixis: The precise term for seed formation without fertilization, circumventing sexual reproduction.
Polyembryony: The development of multiple embryos from a single fertilized egg; unrelated to seed formation without fertilization.
Syngamy: The union of two gametes during sexual reproduction, resulting in fertilization.
Therefore, apomixis is the accurate term for seeds formed without fertilization.
