Müntzing in Hereditas XIII. 293 Auto-polyploids, however, are generally less stable than the diploid parents. 1930[see allopolyploidy]. 1945Lancet 14 July 47/2 Colchicine possesses the property of arresting cells in the process of mitotic division at a stage when the chromosomes have divided and the cytoplasm is undivided, so that a cell with a double complement of chromosomes results... This process of doubling is called autopolyploidy, and the products autopolyploids. 1952New Biol.
