Failure of chromosome pairing was observed in all the presently investigated natural populations of Erigeron karvinskianus (2n=36). All 4 populations were observed with a different range of univalents besides bivalents at diakinesis and metaphase I. The presence of univalents bound with various other meiotic irregularities, such as laggards and chromatin bridges, which further lead to abnormal microsporogenesis. Pollen sterility was found to be high.
