Comparison of the Karyotypes and G-banding Patterns between Domestic Fowl (Gallus domesticus) and Quail(Coturnix coturnix)

Karyotype analysis was carried out on domestic fowls and quails using the peripheral lymphocyte culture techniques and G-banding patterns were obtained with trypsin and Giemsa staining.The results showed that the domestic fowl and quail had a diploid number of 78.But their positions of centromere of macrochromosomes were different from each other.NO.1 chromosome was metacentric,while that of quail was submetacentric.Besides,NO.4,6,8,Z chromosome of domestic fowl were submetacentric,submetacentric,metacentric,metacentric,repectively,whereas those of quail were all telocentric.Additionally,analysis of G-banding patterns for macrochromosomes of them indicated that there was great difference between NO.1 and NO.2 chromosome,which can be explained by the pericentric inversions.
