| Abstract: | Typology and the number of chromosomes were studied in two species of domestic poultry: the domestic fowl (Gallus domesticus) and duck (Anas platyrhynchos domestica). The classical method, described by Konstantinov and Dobriyanov (1974), used in the trails, enabled typology only in the largest chromosomes. In the remaining microchromosomes the position of centromere was not determined. Microchromosomes appeared as points which were arranged by size in caryotypes. The domestic fowl had 78 chromosomes on the whole and the duck 80 chromosomes. |
