dc.description.abstractChromosomal studies were carried out on Eichhornia crassipes and the taxon was found to have 32 individual chromosomes with haploid chromosome number of 16 (n=16), indicating a clear tetraploid genome of 2n =4x =32, chiasmata frequencies per nucleus/bivalent were analyzed at diplotene and diakinesis revealing a marked reduction of chiasmata at diakinesis as compared tobdiplotene . the very low terminalization value of 0.43 showed that most of the chiasmata were terminalized at diakinesis and metaphase I. Multivalent associations were frequent suggesting the presence of a translocation heterozygote . Univalents were also frequent occurrence .chromatid bridges , fragment, Laggards and eliminated chromosomes were also frequent at both MI and MII. Secondary association of chromosomes occurred with a prepodence of four and eight over other groups.en_US
