Popis:	The cytogenetic peculiarities of the genesis of apical meristem cells in apomicts were analyzed using some Asteraceae species as an example. It has been revealed that the frequency of aneu- and mixoploids is so high among the plants of these species (up to 30–60% of all plants studied or their progeny) that there is every reason to say that their occurrence in apomicts is regular rather than spontaneous. It has been demonstrated that microgametophyte in aposporous facultative apomict Pilosella officinarum is a relatively stable element of the seed reproduction system in terms of the ploidy level.
