CHROMOSOME-BANDING PATTERNS OF INDIAN DOMESTIC PIG

Various banding techniques have been used to characterize the architec ture of chromosomes of Indian domestic pigs (desi). The banding techni ques used in karyotype analysis were conventional staining, trypsin G- banding, C- banding and NOR - banding. The desi pig contained 38 chro mosomes. G-banding results are quite comparable with the standard G-ba nded karyotype as described by Reading Conference. Similarly no differ ences were observed in G-, C- and NOR- banding patterns between desi a nd Landrace pig breeds. However, C-banding showed some variation, but the variation is individual specific. The results also suggested that the C-banding is not uniform in each karyotype. This resulted in 3 typ es of heterochromatin in the genomes of Indian domestic pig.
