[Typing and number of chromosomes in the common pheasant and rock partridge]

The typology and number of chromosomes were studied in two species of feathered game: common pheasant and rock partridge. The use of the traditional method of bone marrow processing after Konstantinov and Dobriyanov (1974) made it possible in the studied species to form the caryotypes, even despite the problems encountered in avian cytogenetics. Chromosome typology was possible only in the largest chromosomes. In the remaining microchromosomes the position of centromere was not determined and the microchromosomes themselves appeared as points arranged by size in caryotypes. The number of chromosomes in common pheasant and rock partridge was 80.
