In clone VII, the meiotic irregularity in the pollen grain has been found to be much higher than that in the pollen mother cell (PMC) It is suggested that this is due to events at interphase after the second meiotic division. In clones V and VI, the percentage of meiotic irregularity in PMCs is much higher than in the pollen grains. This has been attributed either to restitution of broken ends or to severe genic change causing loss of dividing capacity of pollen grain nuclei, thus eliminating the irregularities during analysis.Read More
