autopolyploida type of POLYPLOID in which there has been duplication of the number of each chromosome, all chromosomes coming from the same original species. For example, in Fig. 57, A represents one complete set of chromosomes. Like an ALLOPOLYPLOID, an autopolyploid is a mechanism for creating new species, particularly in plants. Allopolyploids are more successful, perhaps because autopolyploid chromosomes have pairing difficulties at MEIOSIS.
