Apogeny
Definition
A rare form of asexual reproduction or embryonic development where offspring arise without a fertilization phase or genetic fusion, maintaining the maternal organism's characteristics unchanged; a particular type of apomixis. In cytogenetic studies, the term denotes the absence of functional gamete formation or fusion, dictating a strict structural stability of clonal lines.
