#anisomer

• Anisomer — An asymmetric isomer or a compound substance formed by molecules whose segments or atomic groups do not present an equal ratio of geometric, structural, or molecular mass symmetry. As an adjective, it describes a state, chemical bond, or macromolecular process characterized by the inequality of components or polymeric segments, causing divergent physico-chemical properties.
• Anisomerogamy — A type of primitive sexual reproduction where fusion occurs between motile gametes that are unequal in size but similar in external structural shape. It represents an intermediate phase in the evolution of cellular reproduction, situated between isogamy (identical gametes) and oogamy (totally differentiated gametes), providing an initial functional differentiation between the smaller male and larger female sex cells.
