Meiosis In the meiotic divisions the distinction between the leontodontoides and parviflora chromosomes is not so great as in the hybrid with tec- torum, but the behavior of the chromosomes is rather similar. The same variation in the amount of pairing occurs, but more regular pair- ing is more frequent. Thus at diakinesis and I-M, 4n + li are seen more frequently than in the hybrid with tectorum, but 9i are also
