Comments (Primary source): Researchers estimate that the total rate of autotetraploid formation is of the same order as the genic mutation rate (10^-5) and that a high frequency of interspecific hybridization (0.2% for selfing taxa, 2.7% for outcrossing taxa) is required for the rate of tetraploid formation via allopolyploidy to equal that by autopolyploidy.
