What is the critical distinction between allopolyploidy and autopolyploidy?
A) Allopolyploidy involves disruptive selection; autopolyploidy does not
B) Autopolyploidy involves disruptive selection; allopolyploidy does not
C) If speciation is allopatric rather than sympatric, the mode of speciation is allopolyploidy; if speciation is sympatric rather than allopatric, the mode of speciation is autopolyploidy
D) In autopolyploidy, one parental species contributes to the polyploidy; in allopolyploidy, two parental species contribute to the polyploidy
E) In allopolyploidy, one parental species contributes to the polyploidy; in autopolyploidy, two parental species contribute to the polyploidy

Question

Autopolyploidy involves the duplication of a single species' genome, resulting in a polyploid individual with multiple sets of chromosomes from the same species. In contrast, allopolyploidy involves the hybridization of two different species, resulting in a polyploid individual with chromosomes from both parent species. Therefore, in allopolyploidy, two parental species contribute to the polyploidy, while in autopolyploidy, only one parental species contributes to the polyploidy.
