Autopolyploidy refers to the duplication of chromosomes within a single species, resulting in an individual with multiple sets of chromosomes from the same species. Autopolyploid plants can arise through various mechanisms, such as errors during cell division or through the fusion of unreduced gametes.

While allopolyploidy is indeed prevalent in many crop plants, autopolyploidy can also occur in certain species. Autopolyploidy can contribute to the genetic diversity of crop plants and can be advantageous for their adaptation to different environments. Hence, the correct answer is option 1.
