Abstract
Supernumerary chromosomes have been observed in a few individuals of three subspecies of Rattus rattus from India and Nepal. The supernumerary chromosomes are late replicating and positively heteropycnotic during meiosis which characterize their heterochromatic nature. Their G-banding patterns do not exactly resemble the patterns exhibited by the chromosomes of similar size and morphology of the normal complement. The supernumerary chromosomes become conspicuous for the lack of a centromeric C-band in them as compared to the prominent C-bands in other chromosomes of the complement.
