Variations in the satellited chromosomes ofCicer arietinum Linn.

  • G. Meenakshi
  • M. K. Subramaniam


The diversity in the morphology of the SAT-chromosomes ofC. arietinum in different roots are analysed in the context of similar variations observed in the different cells of one of the roots. Intergrades between the two pairs of chromosomes with normal satellites and those with tandem ones were observed in anaphases. The differences in the number as well as the size of the SAT-grains of replicated chromosomes indicate that non-reciprocal translocations between sister chromosomes may be of parts of SAT-grains and not of entire ones.
