Progeny resulting from asexual reproduction from an organism (gr. twig 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 a parent plant. In the process, genetically completely identical organisms with hereditary characteristics are first 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 in small steps from the original vine. However, only after a certain amount of morphological and genetic change can one speak of mutants.
