As the cytological details of the microsporogenesis of the Jute species have not been worked out by any of the above investigators the present investigation of the same is undertaken with special reference to the structure of the early prophase chromosomes of meiosis afld the results with the discussion of some of the fundamental problems of meiosis arising therefrom form the subject of this pap [...] In the case of simultaneous division the heterotypic anaphase chromosomes on reaching the poles get arranged themselves at the equitorial region of either poles and after the usual splitting of the chromosomes prior to the mitotic separation move to the poles and the daughter chromosomes of the three of the developing microspores could be seen at three corners in one plane with the bipolar spind [...] The duality of the early prophase threads with the absence of the scalled `chromomeres' demonstrated and discussed above has important bearing on some of the theories of the cause of pairing and disjunction of the homolgous bivalents in meiosis. [...] If the force of attraction of the homologous genes at the ends of the threads are greater than that of the genes in the middle region an end to end association is initiated as Seen in most of the bivalents of the present material. [...] The hypothesis that the cause of pairing and disjunction is due to the attraction between pairs and the repulsion between pairs of pairs is shown to be untenable in the light of the duality of the early prophase threads demonstrated in the present material.
