Abstract
Gene flow between the two sexual forms is asymmetrical in gynodioecious species: genes are transferred from male-fertile individuals (mF, hermaphrodites) to male-sterile individuals (mS, females) by pollen but from mS to MF individuals by diploid seeds. This situation is expected to cause differences in the genetic make up of mF and mS individuals. The expected differences were found in an experiment on a natural population of the gynodioecious species, Thymus vulgaris L. (thyme). The effectiveness of gynodioecy as a means of regulating heterozygosity and adaptability to various conditions of the environment is discussed.Keywords
