Apomixis
Definition
A biological phenomenon and mode of asexual reproduction in higher plants (angiosperms and pteridophytes) consisting of embryo formation and viable seed production directly from the ovule's maternal tissues, without gametic fusion and without fertilization occurring; natural seed cloning. It represents a major evolutionary strategy studied in phytogenetics for the integral preservation of the maternal genotype.
