Why during vegetative propagation is not observed splitting of characters in the offspring?

Simple heredity is observed during vegetative propagation, that is, when a new individual is formed from the vegetative part of an already existing individual, spores. It is widespread in plants, bacteria, protozoa, sponges, intestinal and some other animals prone to asexual reproduction. Simple heredity is manifested during reproduction, both by specialized cells (spores), and by peculiar organs of vegetative propagation (tubers, bulbs, brood buds, etc.). The category of complex heredity extends to all cases when development begins from the egg, including parthenogenesis. During vegetative propagation, the properties of one individual are transmitted to the offspring, while during the sexual process, the zygote, from which a new individual will develop, carries hereditary information from two organisms. It is quite obvious that in the latter case, the patterns of inheritance of parental properties turn out to be more complex and more diverse.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
