DNA replication, G- and C-bands and meiotic behaviour of supernumerary chromosomes of Rattus rattus (Linn.)

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 no...
