The Chromosome preparations were made from myelocvtes of Muscovy duck,white feather egg-laying duck and their F1 hybrid.The metaphase chromosomes in mitotic cells were ana-lyzed.The diploid chromosome number with few exceptions in these ducks was 78.Pair 1 chromo-somes of Muscovy duck were submetacentric,White feather egg-laying duck′s chromosomes were metacentric;Pair 2 chromosomes of Muscovy duck and White feather egg-laying duck were meta-centric;sex chromosornes were zz/zw,Z chromosomes of Muscovy duck were telocentric,White feather egg-laying duck was actocentric,The other chromosomes were telocentriC.The dif-ferent karyotype in pair 1 and Z chromosome of Muscovy duck and Whlte feather egglaying duck was the major reason of infertility in their F1.
