Offspring produced from an organism by asexual reproduction (Greek: branch or rice). In humans, identical twins form a natural clone (but with different fingerprints). In plants, this is called vegetative reproduction, when new plants are regenerated from certain tissue parts of an initial plant. In the process, genetically completely identical living beings with hereditary characteristics are initially created, which are 100% identical copies (duplicates) of the original type. Due to spontaneously occurring mutations that accumulate during the life phase, these copies slowly but steadily deviate from the original vine in small steps. However, one can only speak of mutants from a certain larger morphological and genetic scope of change.
