1928 C. D. Darlington in Jrnl. Genetics 19 243 A useful distinction has been made amongst polyploids..according as their gametic complements are constituted by the reduplication of similar series (auto-polyploidy), that is, by the doubling of the chromosome number in a theoretically pure line, or by the combination of dissimilar series (allopolyploidy), that is, by doubling in a hybrid.
1945 Lancet 14 July 47/2 Colchicine possesses the property of arresting cells in the process of mitotic division..so that a cell with a double complement of chromosomes results... This process of doubling is called autopolyploidy, and the products autopolyploids.
2008 B. A. Pierce Genetics (ed. 3) ix. 257 The sterility that usually accompanies autopolyploidy has been exploited in agriculture.
