GIEMSA BANDING IN MALE RAT (RATTUS RATTUS)
ABSTRACT G-banding analysis was carried out on specimens of house rats. The diploid chromosome number of Rattus rattus is 2n=38 and the karyotype formula is 16m + 4sm+ 16a + 1X+1Y. The bands produced were specific for each chromosome pair in this animal. The karyotype by G-banding was prepared for m...

| Summary: | ABSTRACT G-banding analysis was carried out on specimens of house rats. The diploid chromosome number of Rattus rattus is 2n=38 and the karyotype formula is 16m + 4sm+ 16a + 1X+1Y. The bands produced were specific for each chromosome pair in this animal. The karyotype by G-banding was prepared for male rat including 36 autosomes contains 16 metacentric, 4 sub-metacentric and 16 acrocentric chromosomes which were arranged in decreasing order of each group. The male contain 2 different sex chromosomes the X which is sub-metacentric and Y chromosome is acrocentric which have arranged separately.
